TABE Math Computations Practice Test 1
43 x 4 = ?
2/9 + 3/9 = ?
When adding fractions that have the same denominator (the number on the bottom), you simply add the numerators together and keep the denominator the same. So 2/9 + 3/9 = (2+3)/9 = 5/9
What is 20% of 100?
20% is equivalent to 20/100 or 0.2. You find 20% of 100 by multiplying 100 x .2 = 20
3^3 + 1^3 = ?
The answer is (3 x 3 x 3) + (1 x 1 x 1) = 27 + 1 = 28
1542 - 517 = ?
5/8 x 2/6 = ?
When multiplying fractions, multiply both the numerators and denominators. So, 5/8 x 2/6 = (5x2)/(8x6) = 10/48 which is 5/24 when simplified.
30 - (-4) = ?
30 - (-4) is the same as 30 + 4 = 34
8xy - 3xy = ?
When adding or subtracting equations with variables, you keep the variable as a unit. Think of the variable xy as "apples", then the equation becomes 8 apples - 3 apples = 5 apples (or 5xy)
13 รท 5 = ?
5 goes into 13 2 times with a remainder of 3.
9/11 - 5/11 = ?
When subtracting fractions that have the same denominator (the number on the bottom), you simply subtract the numerators and keep the denominator the same. So 9/11 - 5/11 = (9-5)/11 = 4/11
Calculate the average of these numbers: 17,13,7,21,22
In 20 hours, a writer completes 180 pages of his novel. How many pages does he write on average?
180รท20=9
N is the result of adding two numbers. What would be three times the other number if one of the numbers were 6?
๐ฅ+๐ฆ=๐โ๐ฅ=6โ6+๐ฆ=๐โ๐ฆ=๐โ6โ3๐ฆ=3(๐โ6)
What is the largest fraction among the following?
๐ด. 7/9=0.77
๐ต. 2/3=0.66
๐ถ. 3/4=0.75
๐ท. 2/5=0.4
If 3๐ฅโ5=8.5, What is the value of 5๐ฅ+3?
3๐ฅโ5=8.5โ3๐ฅ=8.5+5=13.5โ๐ฅ=13.5/3=4.5
Then; 5๐ฅ+3=5(4.5)+3=22.5+3=25.5
What is the surface area of an isosceles right triangle with a 6 cm long leg?
First, draw an isosceles triangle. Remember that the two sides of the triangle are equal.
Let put a for the legs. Then:
a = 6 โ area of the triangle is:
1/2(6ร6)=36/2=18 ๐๐2
