(1 & 2/3) ft = (1 ft) + (2/3 ft)

(1 & 2/3) ft = 12 inches + 12*(2/3) inches

(1 & 2/3) ft = 12 inches + 8 inches

(1 & 2/3) ft = 20 inches

If the tree grows 5 inches per year, then it will take 4 years to get to 20 inches since 5*4 = 20. You can also divide to get 20/5 = 4.

So it takes 4 years for the tree to grow 1&2/3 feet tall.

Answer:

4 years

Step-by-step explanation:

Okay, so basically write a proportion

5 inches/per year

Then, find out how many inches are in  1 2/3 feet

1 2/3 = 1 8/12

Meaning there 1 2/3 feet is 1 foot and 8 inches. We know a foot is 12 inches. so then you just add 12 + 8 which is 20

Now going back to your proportion

5 inches/ per year =20 inches/x years

We know 5 goes into 20 4 times. Meaning to get to 20, your'e going to have to multiply the numerator by 4. But whatever you do to the numerator, you must do to the denominator. So multiply 1 x 4 which is 4 meaning it is going to take 4 years for the tree to grow 1 2/3 feet.

amid [387]
C. 5 packs of pencils and 3 packs of erasers. it is c because no matter what 20(the pack of erasers) is multiplied by it will always end in a zero, therefore you would have to multiply 12 by a number that would make it a multiple of 20 as well which happens to be 5. 5×12=60 and 3×20=60

CAn you help me with ratios? Mrs. Sturkie mixed 3 quarts of blue paint and 2 quarts of red paint to make purple paint to her cla
fredd [130]
So as we already know the ratio is 3 quarts blue paint to 2 quarts red paint, also written as 3:2. if she only has 1 quart blue paint she will need half of a quart of red paint because the ratio has to remain the same amount. if you multiply one side then you must multiply the other. same goes with division. If she only has 1 quart of red paint then that shows she divided the 2 red by 2. There fore you would have to divided the 3 by 2 in order to get 1.5 which would then make the ratio 1.5:1
