The number is 2 because it multiply by 2 and 3
Answer : This is because when 5z minus 5z, it is nullified, with no way to determine the value of z. 5z - 5z = 0
That is why there is no solution for this equation.

Left side gets 12.
Right side gets 16.
12+16=28 in total.
When you're thinking of ratios, you have to think of rounds. Let's say I
want to distribute apples... In Round 1, I'm going to give myself 1
apple and give you 2 apples. After Round 1, three apples have been
distributed in total. Now, if I repeat the same pattern of distribution
1:2, after Round 2 I should have 2 apples whilst you have 4. After Round
2 a total of 6 apples would have been distributed.If the ratio is 3 to 4 - imagine there are 7 groups total, and one person gets 3 of the 7 and the other person gets 4 of the 7.
____________________________________________
If 28 is divided into 7 groups, each group has 4 cans.
One person gets 3 groups = 4*3 = 12 cans
The other gets 4 groups = 4*4* = 16 cans
This way is easier for me to do, but go with whatever works for you :)
Answer:
60 maths books
Step-by-step explanation:
<u>Let the following be:</u>
- Maths books = m
- Science books = s
- History books = h
<u>And we have ratios and sum:</u>
- m/s = 3/2
- s/h = 1/3
- m+s+h = 220
<u>From the ratios we get:</u>
<u>Considering the above in the sum of books:</u>
- m+s+h = 220
- 3s/2 + s + 3s = 220
- 3s + 2s + 6s = 2*220
- 11s = 440
- s = 440/11
- s = 40
<u>Number of maths books:</u>
