Your cousin gave you $2.98 with which to buy a present. This covered 2/5 of the cost. How much did the present cost.

$7.45

Step-by-step explanation:

Find an equivalent fraction

2/5 = 4/10

Calculate as a percent

4/10 = 40%

Change to a decimal

40% = 0.4

Write as an equation with x representing the unknown amount

0.4 * x = $2.98

Multiply

0.4x = $2.98

Divide both sides of the equation by 0.4

x = $7.45

The present costs $7.45

Hope this helps :)
