43/60 × 42/43 = ? Multiply the Common (Ordinary) Fractions, Online Calculator. Multiplication Operation Explained Step by Step
The numerators and the denominators of the fractions are multiplied separately
These fractions reduce each other:
They have numerators and denominators of equal values.
The fractions: 43/60 × 42/43 = 42/60
Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:
- A fully reduced (simplified) fraction is one with the smallest possible numerator and denominator, one that can no longer be reduced, and it is called an irreducible fraction.
- * By reducing the values of the numerators and denominators of fractions, subsequent calculations become easier to perform.
To reduce a fraction to the lowest terms equivalent divide its numerator and denominator by their greatest common factor, GCF.
- To calculate the GCF, factor the numerator and denominator of the fraction into prime factors.
- Then multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponents (the lowest powers).
The fraction: 42/60
The prime factorizations of the numerator and denominator:
42 = 2 × 3 × 7
60 = 22 × 3 × 5
GCF (42; 60) = 2 × 3 = 6
42/60 =
(42 ÷ 6)/(60 ÷ 6) =
7/10
Yet another method to reduce a fraction:
* To reduce a fraction without calculating the GCF: factor its numerator and denominator, then all the common prime factors are easily identified and crossed out.
42/60 =
(2 × 3 × 7)/(22 × 3 × 5) =
((2 × 3 × 7) ÷ (2 × 3))/((22 × 3 × 5) ÷ (2 × 3)) =
(2 ÷ 2 × 3 ÷ 3 × 7)/(22 ÷ 2 × 3 ÷ 3 × 5) =
(1 × 1 × 7)/(2(2 - 1) × 1 × 5) =
(1 × 1 × 7)/(2 × 1 × 5) =
7/10

Rewrite the fraction
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
7/10 =
7 ÷ 10 =
0.7
As a percentage:
- A percentage value p% is equal to the fraction: p/100, for any decimal number p. So, we need to change the form of the number calculated above, to show a denominator of 100.
- To do that, multiply the number by the fraction 100/100.
- The value of the fraction 100/100 = 1, so by multiplying the number by this fraction the result is not changing, only the form.
0.7 =
0.7 × 100/100 =
(0.7 × 100)/100 =
70/100 =
70%
