Question

8) Tammy uses 1 3/4 cups of laundry detergent per load. When she was finished

Answer 1

Tammy uses 1 3/4 cups of laundry detergent. The number of loads is 4

Solution:

Given that, Tammy uses 1 3/4 cups of laundry detergent per load.  

When she was finished doing laundry one day.  

She noticed that she had used 7 cups of laundry detergent.  

We have to find how many loads did she do?

Now, we know that, Total cups used can be written as:

number of loads x number of cups per each load = total cups used.

$\begin{array}{l}{\text { Then, number of loads } \times 1 \frac{3}{4}=7} \\\\ {\text { Number of loads } \times \frac{1 \times 4+3}{4}=7} \\\\ {\text { Number of loads } \times \frac{7}{4}=7} \\\\ {\text { Number of loads }=7 \times \frac{4}{7}=4}\end{array}$

Hence, the number of loads are 4.
