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%



The final answer:
written in three ways

As a positive proper fraction:
(the numerator < the denominator)
43/60 × 42/43 = 7/10

As a decimal number:
43/60 × 42/43 = 0.7

As a percentage:
43/60 × 42/43 = 70%
