Translate and solve using proportions 6.5% of what number is $3.77

The quantity is US$ 58, which 6.5% is US$ 3.77

Step-by-step explanation:

Number = x

6.5% of x = $ 3.77

6.5% = 0.065 = 65/1,000 = 13/200 (Dividing by 5)

3.77 = 3 + 77/100 (We can't simplify 77/100)

Thus,

13/200 * x = 3 77/100

13x/200 = 377/100

13x = 754 (Multiplying by 200 at both sides)

x = 754/13 (Dividing by 13 at both sides)

x = 58
