Estimate: 70$\times$130 = 9100 inch Exact = $9132\frac{1}{2}$inch
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
