What is1/12+7/9. I need help.

Katarina [22]

You have to make them have their least common denominator to add or subtract, in this case 36.
Multiply 1/12 by 3, to get the denominator 36: 3/36.
Multiply 7/9 by 4, to get the denominator 36: 28/36.
Now add the numerators: 3+28=31, 31/36 is as simplified as possible so your answer is 31/36 :) I hope this helps :)

Movies at the rental store are $3.75 each. Snacks and drinks are $1.89 each. Round each amount to the nearest dollar to estimate

hodyreva [135]

Answer:

$14.00

Step-by-step explanation:

First you round 3.75 to 4.00 because 7 is greater than 5 so it would turn the 3 to 4 than add the zeros it's 4.00. Second You multiply by three so 4.00 × 3 you will get 12.00. Than you round 1.89 to 2.00 because 8 is greater than 5 so it would turn to the 1 to the 2 than add the zeros it's 2.00. Finally you add them together and get $14.00

A candle maker has 4 1/2 pounds of clear wax. He wants to cut the wax into pieces that are 2/3 pound each. How many 2/3 pound pi

prisoha [69]

Answer:

a) 10 pieces of 2/3 pound can be made.

b) 0.54 pounds of wax is left over.

Step-by-step explanation:

Total amount of clear wax available = $4\frac{1}{2} = \frac{9}{2}$ pounds

So, the maker has in total 4.5 pounds of wax

Now, The weight of each piece = $\frac{2}{3} = 0.66$ pounds

To find the number of pieces that can be made out of 4.5 pounds of wax,

let that number = n

So, $n = \frac{\textrm{Total weight of the clear wax}}{\textrm{Weight of each wax}}$

or, n = $n = \frac{4.5}{0.66} = 6.81$

So, nearly 6 pieces can be made completely out of the clear wax

Left over amount of wax = Total weight - Weights of the pieces made

= 4.5- 6(0.66)

= 0.54 pounds

Hence, 0.54 pounds of wax is left over
