Test: Simplifying fractions - Year 8 MCQ

The HCF of 33 and 66 is 33, as 33 divides both numbers, resulting in 33 ÷ 33 = 1 and 66 ÷ 33 = 2.

The HCF of 33 and 66 is 33. Dividing both by 33 gives 33 ÷ 33 = 1 and 66 ÷ 33 = 2, so 33/66 = 1/2.

The HCF of 9 and 81 is 9. Dividing both by 9 gives 9 ÷ 9 = 1 and 81 ÷ 9 = 9, so 9/81 = 1/9.

Divide 12 and 18 by 6 to get 12 ÷ 6 = 2 and 18 ÷ 6 = 3, so 12/18 = 2/3.

The HCF of 30 and 40 is 10. Dividing both by 10 gives 30 ÷ 10 = 3 and 40 ÷ 10 = 4, so 30/40 = 3/4.

The factors of 12 are 1, 2, 3, 4, 6, 12, and the factors of 18 are 1, 2, 3, 6, 9, 18. The HCF is 6.

The highest common factor (HCF) of 18 and 24 is 6. Dividing both the numerator and the denominator by 6, we get 18 ÷ 6 = 3 and 24 ÷ 6 = 4. Thus, 18/24 simplifies to 3/4.

The HCF of 10 and 100 is 10. Dividing both by 10 gives 10 ÷ 10 = 1 and 100 ÷ 10 = 10, so 10/100 = 1/10.

The highest common factor (HCF) of 4 and 16 is 4.

Dividing both the numerator and the denominator by 4, we get 4 ÷ 4 = 1 and 16 ÷ 4 = 4.

Thus, 4/16 simplifies to 1/4.

The highest common factor (HCF) of 45 and 60 is 15.

Dividing both the numerator and the denominator by 15, we get 45 ÷ 15 = 3 and 60 ÷ 15 = 4.

Thus, 45/60 simplifies to 3/4.
