Respuesta :
3/4 cup flour 1 cup flour
----------------- = --------------
1 1/8 tsp salt x tsp salt
using cross products
3/4 * x = 1 1/8 * 1
change the mixed number (1 1/8 to an improper fraction = 9/8)
3/4 x =9/8
multiply each side by 4/3
3/4 x * 4/3 = 9/8 * 4/3
x = 36/24
x =3/2
x= 1 1/2 tsp salt
Answer: 1 and 1/2
Step-by-step explanation:
I used the expression 3/4 over 1 and 1/8 = 1 cup of flour over x amount of salt. So I turned 1 and 1/8 into a mixed number. So I multiplied the denominator by the whole number and added it to the numerator and kept the denominator the same. So I got 9/8—using KCF (keep change flip).
9/8*4/3=36/24 and that as a mixed number is 1 and 12/24 which simplified equals 1 and 1/2
