Correct answer: $28.50
A cookbook costs $9.50, making three cookbooks cost $28.50.
Correct answer: 60
80% of 60 equals 48. The simplest method is to report to 10, 8 versus 10, then multiply by 6 to get 48 and 60.
Correct answer: 50
We have three pink balls and ten green balls for a total of 13 balls. Divide 65 by 13 to get 5, which equals 15 pink balls (5 times 3) and 50 green balls (5 times 10).
Correct answer: 63
1 + 2 (3) + 4 (7) + 8 (15) + 16 (31) + 32 (63).
Correct answer: 0.04
0.04 is the smallest value.
Correct answer: $9
Mike pays only the price for 6 scoops of ice cream by purchasing 8 scoops in total. As a result, he pays 6 times $1.50, for a total of $9.
Correct answer: 8
1 + 9 (10) - 8 (2) + 7 (9) - 6 (3) + 5 (8).
Correct answer: 115
30% of 50 equals 15% of 100, so 15. Adding the 50 children from Thursday and the 50-15 children from Friday produces a total of 115 children.
Correct answer: $48
Without the discount, 4 kilos cost $20. A 20% discount on this $20 is equal to $4 (we do 10% and multiply by 2), for a total of $16 for 4 kilos. Jocelyn pays $48 for 12 kilos by multiplying $16 by three.
Correct answer: 1.8
1.8 is the greatest value.
Correct answer: 100
The 20% of 100 which is 100 x .20 equals 20.
Correct answer: 3/8
The fractions must have same denominator in order to be added. In this case, the answer is 8. 1/4 cup equals 2/8, so 2/8 + 1/8 equals 3/8.
Correct answer: 250
Multiply the speed by the time to calculate the distance. For the first part of the journey, that's 65 miles per hour multiplied by 2 hours equals 130 miles. For the second part, multiply 40 miles per hour by 3 hours to get 120 miles. That adds up to a total distance of 250 miles.
Correct answer: 328
Divide the total by the number of seasons to get the average. As a result, the total can be calculated by multiplying the average by the number of seasons. 8 x 41 = 328 in this case.
Correct answer: 8
Each number in the series is half the number that came before it. Because half of 16 equals 8.
Correct answer: 1 cup
We increased the number of cookies by a factor of (24/18) when we made two dozen (24) cookies. As a result, we must multiply 3/4 by 24/18 to obtain the new amount of sugar: 3/424/18 = 324/418 = 1
Correct answer: 7
Examine the differences between the terms, which are placed in brackets between the terms. 13 (-4), 9 (+5), 14 (-6), 8 (+7), 15...
The next term should be obtained by subtracting 8 from 15. 15-8=7.
Correct answer: 60
The rule is as follows: 1, 2, 3, 4, 5... alternating pairs of multiplications and divisions applied to a sub-series that grows by one every time the next operation should be 6, which results in 106=60.
Correct answer: 34
Ezra's sister is twice his age, so her age is now 15*2=30. In four years, Ezra will be 19, which means his sister will be (30+4)=34.
Correct answer: 20
The series rule is: 3, 2, 1.... and the cycle repeats.
As a result, after (30÷3=)10 and (10x2=)20, we have 20x1=20.
Correct answer: 300
First, we need to determine how many toilet sinks will be installed over the next four days.
We can use the 10% shortcut to figure out what 20% of 6,000 is: 10% of 6,000 equals 600 (omit one 0), so 20% equals 600*2=1,200.
If the plumber intends to divide his work evenly over four days, we simply divide 1,200 by 4. 1,200/4=300
Correct answer: 25
To determine how many boxes we can purchase, we divide the total amount of money by the price of each box.
To simplify the solution, move the decimal point in both numbers one place to the right:
$2.5/$0.1 is the same as $25.0 / $1.0 = 25/1 = 25.
Correct answer: 132 | 264
The series repeatedly increases by x2, x2, +4.
