(1) 4p²q : 10pq²

tiny-mole [99]

Answer: (1) 2p: 5q.

(2) 3:10.

(3) 5:6.

Step-by-step explanation:

To find : Ratio

(1) 4p²q : 10pq²

$=\dfrac{4p^2q}{10pq^2}\\\\=\dfrac{2p^{2-1}}{5q^{2-1}}\\\\=\dfrac{2p}{5q}$

i.e. Simplified ratio of 4p²q : 10pq² is 2p: 5q.

(2) 9 months : 2½ years

1 year = 12 months

$2\dfrac{1}{2}\text{years}=\dfrac{5}{2}\text{years}\\\\=\dfrac{5}{2}\times12=30\text{ months}$

Now, 9 months : 2½ years = $\dfrac{9\text{ months}}{30\text{ months}}=\dfrac{3}{10}$

Hence, Simplified ratio of 9 months : 2½ years is 3:10.

(3) 5 m : 600 cm

1 m = 100 cm

So, 5m = 500 cm

Now, 5 m : 600 cm = $\dfrac{500\ cm}{600\ cm}=\dfrac{5}{6}$

Hence, Simplified ratio of 5 m : 600 cm is 5:6.

3/4h-9=1/4h-1 i need help

Vlada [557]

<u> Answer I got for this was 16.

Subtract the 1/4 from the 3/4 and get 2/4, simplified: 1/2

You should have 1/2 h -9 = -1 by now,
Then add nine to the other side, getting 8.
You should have 1/2 h = 8.
Then divide 1/2 by 8.
8/1÷1/2 ---> 8/1 × 2/1 (you flip the fraction when you divide)
So your answer is 16!
Hopefully that helped!</u>
