Simplify 252 over 288

Mathematics
1 answer:
dalvyx [7]3 years ago
8 0
So,

We have to prime factor the fraction.
\frac{252}{288} --\ \textgreater \   \frac{2*2*3*3*7}{2*2*2*2*2*3*3}

Cross out ones.
\frac{7}{2*2*2}

Multiply it out.
\frac{7}{8}

The fraction is now simplified.

A 20% acid solution is mixed with 20 liters of a 45% acid solution. How much of a 30% acid solution will result?
vaieri [72.5K]

Answer:

50 liters

Step-by-step explanation:

If x is the volume of 20% acid, then:

x (0.20) + 20 (0.45) = (x + 20) (0.30)

0.2x + 9 = 0.3x + 6

3 = 0.1x

x = 30

30 liters of 20% acid are needed, so there will be a total of 50 liters of 30% acid.
