How can I do ratios? I’ve been having a lot of trouble with this in my math class, and really need some help.
Katarina [22]

If you have a fraction, take one number and put a different number on top or underneath, for example if you have 2 cats and 3 dogs, the ratio from cats to dogs would be 2:3 but if you did 2 cats to the total number of animals, you would add 2 and 3 and get 5, so the ratio would be 2:5.

Heather has divided ​$5900 between two​ investments, one paying 9%, the other paying 4​%. if the return on her investment is ​$3
Leni [432]

Heather invested $2,200 at 9% and invested $3,700 at 4%

What represents the amount invested in each asset?

The amount invested at 9% can be represented as x whereas the balance invested at 4% is (5900-x), as a result, the interest earned on each is computed thus:

Interest 9%=x*9%

interest at 9%=0.09x

Interest at 4%=(5900-x)*4%

interest at 4%=236-0.04x

Total interest=0.09x+236-0.04x

total interest=0.05x+236

Total interest earned=346

346=0.05x+236

346-236=0.05x

110=0.05x

x=110/0.05

x=$2,200(invested at 9%)

amount invested at 4%=5900-2200

amount invested at 4%=$3,700
