Let’s make x = # of nickels. Then 3x = # of dimes and 3x+6 = # of pennies. A nickel is 5 cents, a dime is 10 cents and a penny is 1 cent.
The money she has should be .05(x) + .10(3x) + .01(3x+6) = 4.62 or to make it simpler: 5(x) + 10(3x) + 1(3x+6) = 462.
5x + 30x + 3x + 6 = 462
38x + 6 = 462
38x = 456
x = 12.
So she has 12 nickels (12 * $0.05 = $0.60), 36 dimes (36 * $0.10 = $3.60) and 42 pennies (42 * $0.01 = $0.42). $3.60 + $0.60 + $0.42 = $4.62.
the Great Common factor can either be 3 or x.

You have 2 ratios
Recipe
115 g H
375 g F
115/375
Mrs. Tanaka's limitations
46 H
? F
Equate these two
115/375 = 46/x Cross multiply
115x = 375 * 46 Combine the right
115x = 17250 Divide by 115
115/115 x = 17250/115 Divide
x = 150 grams of flour,
