Question

4. Miguel is helping his mom paint his home. He finished 2 rooms in ⅓ of an hour. How many rooms can he paint in 1 hour?

Answer 1

Answer: 6

Explanation:

Let's use a rule of three here.

2 rooms in 1/3 h

x rooms in 1 h

`(2)/(x)=((1)/(3) )/(1)`

Solve for x;

`x=(2*1)/((1)/(3) )`

Remember that when you divide by a fraction, you invert the fraction and multiply by the numerator.

1/3 inverted is 3/1 or 3

`x=(2*1)*3`

`x=(2)*3\\x=6`
