First, convert your mixed numbers into improper fractions, so 8+3/8=69/8 and 2+1/3=7/3. Now you have 69/8=r-(7/3). Now, add 7/3 to both sides, so (69/8)+(7/3)=r. Now, just add your fractions, so (69/8)+(7/3)=207/24+56/24=(207+56)/24=263/24. If you need to, this can be converted back into the mixed number 10+23/24.
A im getting outta my version
3x-2y=-16
-16-3x= -2y
Divide by -2 both sides
-16/2-3x/2=y
y= 8+3/2x
Well if you already know how to write an equation for a given set of proportions, then all you have to do is replace the unknown value with x, and then cross multiply and solve the equation. One important thing to remember is that for each proportion the numerator and the denominator have to be of the same units in the equation.
Answer:
18 melon
Step-by-step explanation:
Given :
Original stack :
Melon = 45
Grape fruits = 60
Mini version :
Grapefruit = 24
Using grapefruit ; we can obtain the scale factor;
60 : 24 = 2.5 : 1
Hence,
Amount of melon in the mini version is :
45 / 2.5
= 18
