If three quarters of a number decreased by twenty is equal to eighty two, what is that number?
Studentka2010 [4]

A number is :

x

_________________________________

Three quarters of it means :

\frac{3}{4}x \\

_________________________________

Decrease by 20 means :

\frac{3}{4}x - 20 \\

_________________________________

Equals to 82 means :

\frac{3}{4}x - 20 = 82 \\

_________________________________

What is that number ?

x asked so we must solve the above equation for x.

Let's do it....

\frac{3}{4}x - 20 = 82 \\

Plus sides 20

\frac{3}{4}x = 82 + 20 \\

\frac{3}{4}x = 102 \\

Multiply sides by 4

3x = 102 \times 4

Divided sides by 3

x =  \frac{102 \times 4}{3} \\

x =  \frac{102}{3} \times 4 \\

Simplify

x = 34 \times 4

x = 136

So that number is 136 .

_________________________________

And we're done.

Thanks for watching buddy good luck.

Order from least to greatest: 2/3, 25%, 3/5, 0.40 with work
Evgesh-ka [11]

Answer:

Order from Least to Greatest

1/4  <  4/10  <  3/5  <  2/3

Showing Work

Rewriting as fractions if necessary:

2/3, 1/4, 3/5, 4/10

The least common denominator (LCD) is: 60.

Rewriting as equivalent fractions with the LCD:

40/60, 15/60, 36/60, 24/60

Ordering these fractions by the numerator in order from least to greatest:

15/60 < 24/60 < 36/60 < 40/60

Therefore, your input in order from least to greatest is:

1/4 < 4/10 < 3/5 < 2/3
