Question

Ingrid gets two - thirds of her essay typed in 30 minutes. The equation 2/3×=30 can be used to find out how long it will take her to type her essay. Solve the equation to find the total number of minutes it takes for Ingrid to write the essay. Use numbers and words to explain how to solve 2/3×=30

Answer 1

Answer:

The answer is 45

Step-by-step explanation:

The equation is a straightforward one, we have:

2/3x = 30

because we have a fraction on at least one side, we will cross multiply thus:

2x = 30 x 3

2x = 90

Next, we divide both sides by 2 to make x the subject of the formula, we have 2x/2 = 90/2

x = 45

Therefore, it takes Ingrid 45 minutes to complete her essay
