Step-by-step explanation:
come on ! you can literally see that in the chart.
how many parts of the gray 3/8 are covered by the gray 1/4 ?
2 parts = 2/8 are clearly covered by 1/4.
2/8 is what part of 3/8 ?
it is the same question as "2 is what part of 3" ?
is 2 a quarter (1/4) of 3 ? no, 1/4×3 = 3/4 and not 2.
is 2 one third (1/3) of 3 ? no, 1/3 of 3 = 1/3×3 = 1 and not 2.
is 2 two thirds (2/3) of 3 ? ah, 2/3 × 3 = 2. that is correct !
is 2 three quarters (3/4) of 3 ? no, 3/4×3 = 9/4 and not 2.
once you have the same denominator, you can easily compare the numerators and ignore the denominators for such problems.
You have to plug in a random y value and use algebra to solve for x. It is impossible to do without at least one point for y.
All's =a
Bob's =b
Lunar =l
A:B = 4:5 B:C = 6:7
Multiply the two ratios above by 6 and 5 respectively
A:B = 24:30 and B:L=30:35
Now that we have the B's to be the same
Alls:Lunar = 24:35
