If 1/4, 2/3, 4/7, 1/2 are converted to decimals we get 0.25, 0.6666...., 0.571....., 0.5 then the correct order is obvious
or
If 1/4, 2/3, 4/7, and 1/2 are converted to fractions with a common denominator 21/84, 56/84, 48/84, 42/84 then the correct order is obvious.
Divide the number of trees to be planted from the number of trees in each row
1235 ÷ 24 = 51 r 11
The remaining equals the number of trees that have been left over 11
The correct response: 11
y =15 - 3x and y = 0
Hence 15 - 3x = 0
Plug 5 in for x.
15 - 3(5) = 0
x=5
Absolute values (|a| or abs(a)) can be used to find the distance between two numbers.
abs(-3/7 -2/3) is the distance between these two values.
= abs(-(3/7 -2/3))
= abs(3/7 -2/3)
= abs(9/21 - 14/21)
= abs(-5/21 )
=5/21
One third of 84 is 84 × 1/3 = 84÷3 = 28. 28 people 25 years old or younger applied for the job. Two seventh of 84 is 84 × 2/7= 2×84÷7 = 24. 24 people who were at least 50 years old applied for the job. 84 - 28 - 24 = 32. 32 people applied for the job who were between 25 and 50.
After t weeks, h =15 + 3.2t gives the height of a shrub in inches. When a person's height is 31 inches, the answer is 31 = 15 + 3.2t.
16 = 3.2t
t = 163.2 t = 163.2 t = 163.2 t = 16
t = five
After 5 weeks, the height is 31 inches.
