Question
Fill in the blank in the expression with the proper number.
(5 × 4) > (7 × ______)
Solution
(5 × 4) > (7 × 2)
Explanation:
(5 × 4) > (7 × x)
20 > 7x
Divide both sides of the inequality by 7 to isolate x:
`20/7 > x`
The fraction `20/7` is approximately equal to 2.857. Therefore, the blank can be any number less than 2.857. For integers, the largest number satisfying this inequality is 2.
(5 × 4) > (7 × 2)
