Mathematics

First you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100

Then do the same thing to the first number 8 so 8x2=16+8x1.5=20

then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%

Divide 8 by 40 and you get 0.2 or 2 tenths which equals to 20%.

Use a calculator, it always helps.

Listen Rachel babysat three children for five hours if they were paid $2.50 per hour for each child and divided their earnings e
lina2011 [118]

Answer: Each girl will receive $18.75.

Step-by-step explanation:

Given: Two girls babysat three children for five hours.

Hourly pay for each child = $2.50

Payment for 5 hours per child = 5\times\$2.50=\$12.5

Payment to 3 children for 5 hours = 3\times \$12.5=\$37.5

So, the amount received by each girl  = \dfrac{\text{Payment to 3 children for 5 hours}}{2}

=\dfrac{37.5}{2}=\$18.75

Hence, each girl will receive $18.75.

The elephants at the zoo eat 3 2/3 buckets of bananas each day. The zookeeper bought 7 1/3 buckets of bananas. How many days wil
uranmaximum [27]

Answer: 2 days

Step-by-step explanation:

The monkeys eat 3 ²/₃ buckets of bananas each day. Convert this to an improper fraction:

= 3²/₃ = 11/3 buckets per day

The zookeeper bought 7¹/₃ which is:

= 22/3 buckets

To find out the number of days the bananas will last, divide the buckets bought by the buckets eaten per day:

= 22/3 ÷ 11/3

= 22/3 * 3/11

= 66/33

= 2 days

<em>If dividing fractions, multiply by the reciprocal of the second fraction. </em>
