Answer:

1/3

Step-by-step explanation:

Turned 20 minutes, so the minute hand turned 20 times per hour

There are 60 minutes in 1 hour, so the minute hand turns 60 times per hour

Therefore, the fraction is 20/60, simplified to 1/3

For problem number four on the paper I’m confused I don’t know how to do the table with decimals can someone please explain how
Lostsunrise [7]

Answer:

$7.00

Step-by-step explanation:

2.10 \div 6 = 0.35

4a) 1 oz of coffee is equal to 0.35c, which is consistent with everything in the table.

4b)Knowing this, if we have 20 oz of coffee, and we multiply it by 0.35, we will get how much it costs for this cup.

20*0.35 = 7.00

Hope this makes sense and feel free to ask questions!

Jackson’s age was 2/fifth of the age he will be 20 years from now seven years ago. How old is Jackson now?
Margaret [11]
Let's say Jackson's age now is x.

In 20 years, (so 20+x), Jackson seven years ago will be 2/5ths of that age.

So 2/5(20+x)=x-7

Then you solve the equation
8+2/5x=x-7
15=3/5x
x=25
Jackson is 25 years old. 

Let's check our answer! In 20 years, Jackson will be 45. 7 years ago, he was 18. 2/5 of 45 is 18. Our answer is correct!
