Answers

Answer 1

Answer: 3/5 x 7/7= 21/35
4/7x 5/5= 20/35
They both have a common denominator

Answer 2

Answer:

Final answer:

To put the fractions ³/5 and 4/7 over a common denominator, find the least common multiple (LCM) of 5 and 7, which is 35. Multiply the numerator and denominator of each fraction by the appropriate factor to obtain fractions with a denominator of 35.

Explanation:

To put the fractions ³/5 and 4/7 over a common denominator, we need to find the least common multiple (LCM) of 5 and 7.

The multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, ...

The multiples of 7 are: 7, 14, 21, 28, 35, ...

The LCM of 5 and 7 is 35.

To convert ³/5 to have a denominator of 35, we multiply the numerator and denominator by 7. This gives us ³/5 * 7/7 = 21/35.

To convert 4/7 to have a denominator of 35, we multiply the numerator and denominator by 5. This gives us 4/7 * 5/5 = 20/35.

Therefore, the fractions ³/5 and 4/7, when put over a common denominator, are 21/35 and 20/35, respectively.

in a typical symphony orchestra 16 out of every 100 musicians are violinists what fractions of the orchestra are violinists ?

Answers

Answer: Our required fraction is $(4)/(25)$

Step-by-step explanation:

Since we have given that

Total number of musicians = 100

Number of violinists = 16

We need to find the fractions of the orchestra are violinists :

Fraction will be

$=\frac{\text{number of violinists}}{\text{ Total number of musicians}}=(16)/(100)=(4)/(25)$

Hence, our required fraction is $(4)/(25)$

4 out of every 25 musicians are violinists.
