Answer:
1. x=69/40
2. x=3/4
Step-by-step explanation:
#1 steps
1. Convert the decimals to fractions
x/9/20 = 23/100/3/50
2. Simplify the fractions
20x/9 = 23/6
3. Simplify the equation using cross multiplication
6 * 20x = 23 * 9
120x = 207
4. Divide both sides by 120
x = 69/40
#2 steps
1. Simplify the fractions
1/3/1/6 = 3/2/x
2 = 3/2/x
2 = 3/2x
2. Multiply both sides by the equation 2x
4x = 3
3. Divide both sides by 4
x = 3/4
Its helpful because it gives you the number to put in and to find the unit rate
Let
a= melon
b= servings of melon
c= slice of melon
equation 1
a= 6b
equation 2
a= cb
equation 3
2/3a=a-1/3a
2/3 = 6b-1/3a
2/3cb= 6b-1/3cb
6b= cb
c= 6 slices
There are 6 slices per serving, thus Stephen ate 6 slices over the weekend
