Answer:

75 questions

Step-by-step explanation:

Let x = total number of questions

Multiply the number of questions by the percent she got right to equal the number of questions right

x*84 % = 63

Change to decimal form

.84x = 63

Divide by .84

.84x/.84 = 63/.84

x =75

viva [34]

Answer: 3/50

Again,

0.06 = 6 × 10-²

Now 0.06 = 6/100

= 3/50.

Therefore, the fractional form = 3/50 in its lowest term.
