Kenzie finds purple, blue, and silver space rocks while exploring, 2/3 of the rocks are purple and 3/4 of the remainder are blue
Nadya [2.5K]

Answer:

There were 36 space rocks in total.

Step-by-step explanation:

First, you need to find what fraction of the original rocks are silver.

If 2/3 are purple, then 1/3 of them are not.

If 3/4 of the remaining 1/3 are blue, then 3/4 x 1/3 = 3/12 rocks are blue.

2/3 of the rock are purple, 3/12 of them are blue, and the remaining is silver.

So, you need to do 2/3 - 3/12, then find common denominators so, 8/12 - 3/12 which = 1/12.

This means 1/12 of the rocks are silver. If there are silver rocks, you need to find a suitable equation that needs to be solved.

So:

1/12r = 3

r = 36 silver rocks

There were 36 space rocks in total.

hope this helps :)

I have 3 children. Their ages add up to 21, and when multiplied they equal 75. How old are they?
olganol [36]
So represent the ages as x y and z with each being numbers

x+y+z=21
x times y times z=75
this is really tough for elementary school

one way is to find the factors of 75 or the numbers that add up to 75 and trial and error
use whole numbers becuase this is the world of math so


75=1 times 3 times 5 times 5
possible ages are
3,5,5
1,5,15
1,3,25
add them up

3+5+5=13
1+5+15=21 check
1+3+25=29


their ages are 1, 5 and 15
