Answer:
A: tom has 15 more roses than ana does.
B: 11:4
Step-by-step explanation:
A: there is a 3:1 and 5:2 ratio of roses to tulips. that means that in tom's, there are 3 roses for every tulip and 5 roses for every 2 tulips in ana's.
we know that they each have 30 tulips so now for Tom.
3:1 so to find roses, we need to multiply the value of tulips to 3.
3×30=90 so we know he has a total of 90 roses.
for ana: she also has 30 tulips. BUT now her ratio is 5:2. so for every 2 tulips she has 5 roses. we need to divide the value of tulips by 2 so 30/2=15 and multiply it by 5, 15*5=75
THAT IS NOT THE ANSWER!! <em>to find the rest of the answer, we have to subtract tom's amount by ana's amount</em>: 90-75=15
B: to find this answer, we have to add all of the roses together and all of the tulips together. roses: 90+75=165. tulips: 30+30=60.
the ratio we get is 165:60. and now we need to simplify it.
Answer:
6 : 1
Step-by-step explanation:
A unit rate has to be "a number to 1" or "x:1". Here we have a number to 1/4. Multiply both numbers by 4 so the 1/4 becomes 1.
3/2 * 4 = 12/2 = 6
1/4 * 4 = 1
3/2 : 1/4 is the same as 6 : 1
This is pretty easy once you know how to do it.
12+x=? We are given what X is.
So we just plug in X.
12+(9)=21.
21 is the answer
