9/27 is equivalent to 2/27
33 photos in a 4x to 7x ratio
4x + 7x = 33
11x = 33
x = 3
33 photos can be put in a 4(3) to 7(3) ratio
which is a 12 to 21 ratio
so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7
Note:
<span>a(b) = ab = a x b = a times b</span>
Ewan ko po ehh pero pagaaralan ko poi yan
for the above question, we can first convert the fractions to decimals to make it easier to work with
<span>1/10 of sand - 0.1 ton </span>
4/5 minute - 0.8 minute
<span>Q1 - </span>
<span>ratio </span>
0.1:0.8
since the ratio is in decimals we can convert it to whole numbers by multiplying by 10
1:8
Q2. amount of sand added in 0.8 minutes - 0.1 ton
<span> amount of sand added in 1 minute - 0.1/0.8 = 0.125 tons</span>
