To calculate:To write and solve anaddition equation to find how much food Keisha gives the dog the rest of the day

Answer to Problem 28PPS

Equation to find how much food Keisha gives the dog the rest of the dayis $\frac{2}{3}+x=1\frac{1}{2}$

Keisha gives the dog $\frac{5}{6}$ cups of food in the rest of the day

Explanation of Solution

Given information:Keisha feeds her dog $\frac{2}{3}$ cup of food in the morning. She feeds the dog a total of $1\frac{1}{2}$ cups of food every day.

Calculation:

Let Keisha gives $x$ cups of food to the dog the rest of the day.

Given that Keisha feeds her dog $\frac{2}{3}$ cup of food in the morning and she feeds the dog a total of $1\frac{1}{2}$ cups of food every day.

Thus, equation is

$\frac{2}{3}+x=1\frac{1}{2}$

On solving above equation,

> $\begin{array}{l}\frac{2}{3}+x=\frac{3}{2}\\ x=\frac{3}{2}-\frac{2}{3}\\ x=\frac{9}{6}-\frac{4}{6}\\ x=\frac{5}{6}\end{array}$

Hence, Keisha gives the dog $\frac{5}{6}$ cups of food in the rest of the day
