If sally got 28 questions correct and received 70% on the exam, how many questions were on the exam

Mathematics
1 answer:
Furkat [3]3 years ago
7 0

Answer: 40

Step-by-step explanation:

Number of correct questions Sally got = 28 questions

Percentage of correct questions answered= 70% on the exam,

Total number of questions in the exam = Unknown

Let the total questions in the exam be represented as y.

Since Sally got 70% correctly, this will be:

70% of y = 28

70/100 × y = 28

0.7 × y = 28

0.7y = 28

Divide both side by 0.7

0.7y/0.7 = 28/0.7

y = 40

There are 40 questions in the exam.

Turn .055 into fraction
Slav-nsk [51]
Write 0.055 as
0.055
1

Multiply both the numerator and denominator by 10 for each digit after the decimal point.

0.055
1

The factors of 55 are: 1 5 11 55
The factors of 1000 are: 1 2 4 5 8 10 20 25 40 50 100 125 200 250 500 1000
The Greatest Common Factor (GCF) for both 55 and 1000 is: 5
Now to reduce the fraction we divide both the numerator and denominator by the GCF value.

=
0.055 x 1000
1 x 1000
=
55
1000


In order to reduce the fraction find the Greatest Common Factor (GCF) for 55 and 1000. Keep in mind a factor is just a number that divides into another number without any remainder.

Answer ( 55/1000
= 11/200)
