10. On one night, a group of 9 rats carried away 45 kg of food. What is the reduced ratio of rats to food weight

GenaCL600 [577]

Answer:

Number of rats : Food weight = 1 : 5

Step-by-step explanation:

Number of rats in the group = 9

Weight of food carried away by them = 45 kg

Ratio of the number of rats and food weight = $\frac{\text{Number of rats}}{\text{Weight of food carried by the rats}}$

= $\frac{9}{45}$

= $\frac{1\times 9}{5\times 9}$

= $\frac{1}{5}$

Therefore, Number of rats : Food weight = 1 : 5

I WILL MAKE BRAINLEST!!!!!!

Answer:

$\sqrt{\frac{9}{4}}$ < $\frac{5}{3}$ < $\sqrt{5}$ < 2.5

Step-by-step explanation:

Given the following numbers, $\sqrt{\frac{9}{4}}, \sqrt{5}, 2.5, and, \frac{5}{3}$ , let's express each as whole or decimal numbers, to find out the least to the greatest.

$\sqrt{\frac{9}{4}} = \frac{\sqrt{9}}{\sqrt{4}}$

$\frac{3}{2} = 1.5$

$\sqrt{5}$ ≈ 2.2

2.5 (already in decimal form)

$\frac{5}{3}$ ≈ 1.7

From the least to the greatest, we have:

$\sqrt{\frac{9}{4}}$ < $\frac{5}{3}$ < $\sqrt{5}$ < 2.5

Divide £24 in ratio 3:5

Nadya [2.5K]

When i divide into ratio, i like to think of them as units:

so 24 will be divided into units, where the first thing gets 3 units and the second 5 units. In total those are 3+5=8 units.

so each unit will have 24/8=4

so the division into the two numbers is like this: the first one gets 3 units (3*4=12) and the second 5 (5*4=20)
so it's 12:20.
