Simplify 4/1/2 divide 1/1/5

Answers

Answer:

40

Step-by-step explanation:

4/1/2 divide 1/1/5

(4/1/2) / (1/1/5)

= 40

Answer: 3(3)/(4)

Step-by-step explanation:

Convert 4&1/2ths to improper fraction. Use this rule: a&b/c=​ac+b/c

((4*2+1)/(2) )/(1(1)/(5) ) \n\n((9)/(2) )/(1(1)/(5))

Use a&b/c=​ac+b/c again to make 1&1/5ths and improper fraction.

((9)/(2))/((1*5+1)/(5)) =((9)/(2) )/((6)/(5) ) now you need to invert and multiply

(9)/(2)* (5)/(6)=(9*5)/(2*6) =(45)/(12) =(15)/(4) = 3(3)/(4)

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)
