Write 8 is the whole number 11 is the <br>numerator and 20 is the denominator ​
PilotLPTM [1.2K]

Answer:

Fraction: 8 \frac{11}{20}

Decimal: 8.55

Step-by-step explanation:

8 11/20 is the answer because:

1) Since 8 is the whole number, 8 wouldn't be part of the fraction

2) The numerator is the top number in the fraction, so 11 is at the top since 11 is the numerator

3) The denominator is the bottom number in the fraction, so 20 is at the top since 20 is the denominator

8.55 is the answer because:

1) Since 8 is the whole number, 8 would be in front of the decimal point

2) When you multiply the fractions, you have to multiply until you get a hundred. Therefore, 20*5 = 100 and 11*5 = 55

Hope this helps!

Wanda has three times more shirts than her brother, Will. The equation a = 3b, where a represents the number of shirts Wanda has
marusya05 [52]

Answer:

8 shirts

Step-by-step explanation:

Given the equation a = 3b, where

a = the number of shirts  Wanda has

b = the number of shirts Wanda's brother (Will) has

Hence if Wanda has 24 shirts then

24 = 3b

Divide both sides by 3

24/3 = b

b = 8 shirts

Will has 8 shirts.
