1750 shared between 3 people. Ratio 3:5:8. What is the amount of the smallest portion. A population of 120 students is in the ratio of 1:9/ How many students are there to 4 teachers?
add the parts in the ratio... 3 + 5 + 8 = ...?
ok. I did that. Then 1750/16. Got 109.37 Then multiplied by 3 Solution: 328.13.
3x+5x+8x=1750
Ok pgpilot326, I did that.
no just use 3 + 5 + 8 = 1 then to find the value of 1 unit in the ratio its 1750/16 = then multiply the answer by 3 to find the value of 3 part.
same for the other question... 1 + 9 = 10 120/10 = to find 1 prt... then multiply the answer by 4 to find the number of pupils for 4 teahcers
the answer is 3x once you find x. x is the same thing as 1750/16... method matters not... go for understanding.
