Answer:

First blank(reading from top to bottom left to right) : 21 second blank: 21 third blank: 5 fourth blank: 4 fifth blank: 5.25 or 5 and 1/4 or 21/4

Step-by-step explanation:

To solve this you will first need to make 4 and 1/5 into a improper fraction. To do that you multiply 4 and 5 and get 20. Then you add the 1, and get 21. That will go in your first blank. Next you will remember your KCF (Keep Change Flip) rule. Keep the 20/5, change the division sign to a multiplication sign, and flip 4/5 to 5/4. Next you will just multiply across. 21*5=105 5*4=20 The Directions say to have your answer in simplest form. 105/20 is not in it's simplest form. To make 105/20 in simplest form you would just divide. Your answer on a calculator makes out to be: 5.25. That is just 5 and 1/4 in fraction form, or 21/4 in improper fraction form.

If 5/6 gallons of paint covers 1/4 of the house, then how much paint is needed for the entire house?

tia_tia [17]

Answer:

Step-by-step explanation:

1) If $\frac{5}{6}$ is needed to cover $\frac{1}{4}$ than we need 3 more: $\frac{5}{6}(3)=\frac{15}{6} =2\frac{3}{6} gallons2) But we still need to add the beginning [tex]\frac{5}{6}$ : $2\frac{3}{6}+\frac{5}{6}=2\frac{9}{6}=3\frac{3}6}=3.5$
