Chapter 0.2, Problem 15E

To determine

To solve the equation $1\frac{1}{2}gal=?l$

Answer to Problem 15E

  $\frac{3}{2}gal=5.6781l$

Explanation of Solution

Given Information: $1\frac{1}{2}gal=?l$

Formula Used :unit conversion

Calculation:

Given equation is

  $1\frac{1}{2}gal=?l$

So it can be written as-

  $\frac{3}{2}gal=?l$

So

  $1gal=3.7854l$

Hence to calculate $\frac{3}{2}gal$ to litre, multiply both sides by $\frac{3}{2}$ -

  $1gal\times \frac{3}{2}=3.7854l\times \frac{3}{2}$

This gives-

  $\frac{3}{2}gal=3.7854l\times \frac{3}{2}$

Hence the final answer is,

  $\frac{3}{2}gal=5.6781l$
