Evaluate the expression for the given variable. 7-y÷5/8;y=1/4

Sagot :

The given expression is

7-y÷5/8

If we substitute y = 1/4 into the expression, it becomes

7 - 1/4 ÷ 5/8

We would simplify the expression by applying the correct order which is known as PEDMAS where

P represents parenthesis

E represents exponent

D represents division

M represents multiplication

A represents addition

S represents subtraction

Thus, we would carry out division first.

1/4 ÷ 5/8

we can change the division sign to multiplication and flip the fraction. It becomes

1/4 * 8/5 = 2/5

The expression becomes

7 - 2/5

= 33/5
