Answer
Estimate: 70$\times$130 = 9100 inch
Exact = $9132\frac{1}{2} $inch
Work Step by Step
We know that Fles can jump 130times higher then their oen height.
Now, we need to find the how higher a $70\frac{1}{4} inch$ heighted person can jump? Then we need to multiply the height with 130 i.e. = $70\frac{1}{4} \times 130$ inch.
Now, Let's find Estimate :
$70\frac{1}{4} $ (round off) 70
i.e. $70\frac{1}{4} \times 130$ inch = 70$\times$130 = 9100 inch
Now Let's find Exact:
$70\frac{1}{4} \times 130$ inch.
= $\frac{70\times4+1}{4} \times 130$ inch.
= $\frac{281}{4} \times 130$ inch.
= $\frac{281}{2} \times 65$ inch.
= $\frac{18265}{2}$ inch
= $9132\frac{1}{2} $inch
