Multiply or Divide to Find Equivalent Fractions
Multiply or divide to find the equivalent fraction.
Question 1.
_________
Answer:
Let the missing numerator of the equivalent fraction be x.
\(\frac{21}{60}\) = \(\frac{x}{360}\)
x × 60 = 21 × 360
6x = 21 × 36
6x = 756
x = 756/6
x = 126
So, the equivalent fraction is \(\frac{21}{60}\) = \(\frac{126}{360}\)
Question 2.
_________
Answer:
Let the missing numerator of the equivalent fraction be x.
\(\frac{51}{120}\) = \(\frac{x}{360}\)
x × 120 = 51 × 360
12x = 51 × 36
12x = 1836
x = 1836/12
x = 153
So, the equivalent fraction is \(\frac{51}{120}\) = \(\frac{153}{360}\)
Question 3.
_________
Answer:
Let the missing numerator of the equivalent fraction be x.
\(\frac{51}{120}\) = \(\frac{x}{360}\)
x × 180 = 143 × 360
18x = 143 × 36
18x = 5148
x = 5148/18
x = 286
So, the equivalent fraction is \(\frac{143}{180}\) = \(\frac{286}{360}\)
