What is quotient of 6 1/4 divided by 5/8
lara31 [8.8K]

Answer: The quotient = 10

Step-by-step explanation: A quotient is the result you get when a number is used to divide another number. e . g.

6¹/₄  ÷ ⁵/₈ ( where 5/8 is  the divisor )

First convert 6¹/₄ to improper fraction

                       =   25/4 ÷ 5/8

                       =   25/4 × 5/8

                       =    10

The quotient  =   10.

NOTE:  The 5/8 changed to 8/5 because when dividing fractions, immediately you applied the multiplication symbol, the denominator of the divisor becomes the numerator and vice versa
