Answer:X/3X=3

We move all terms to the left:

X/3X-(3)=0

Domain of the equation: 3X!=0

X!=0/3

X!=0

X∈R

We multiply all the terms by the denominator

X-3*3X=0

Wy multiply elements

X-9X=0

We add all the numbers together, and all the variables

-8X=0

X=0/-8

X=0

Five cats each ate 1/4 cup of cat food. How much food did the five cats eat?

qaws [65]

Answer: Five cats ate 1 and a quarter of cat food.

Step-by-step explanation

Given:-

Cat food ate by one cat = 1/4 cup

Cat food ate by five cats = $5\times \frac{1}{4} \text{ [Multiplying both sides with 5 ]}\\\\=\frac{5}{4}=\frac{4+1}{4}=\frac{4}{4}+\frac{1}{4}=1+\frac{1}{4}$ =1 and 1/4 cup.

Therefore cat food ate by five cats = 1 and a quarter of cup.[ here a quarter =1/4]
