Question

Which ratio is greater 7:5 or 9:4

Answer 1

7: 5 =
$\frac{7}{5}$

9: 4 =

$\frac{9}{4}$

$\frac{7}{5} = \frac{9}{4}$
( by cross multiplying)

$7 \times 4 = 9 \times 5 \\ 28 = 45$

$28 < 45$

$\frac{7}{5} < \frac{9}{4}$

7:5 < 9: 4

your answer!!

Answer 2

$\textbf{\huge{Answer:}}$

LCM: It's the Least Common Multiple.

So now, let's take the LCMs of 7:5 and 9:4.

To take out LCM, we multiply the denominators of the fractions we are considering. Here, we have the denominators as 4 and 5. By multiplying them, we get:

5 × 4 = 20

Then;

$\frac{7}{5} \: and \: \frac{9}{4} \\ \\ = > \frac{28}{20} \: and \: \frac{45}{20}$

By this, we get that:

9:4 is greater than 7:5.

9:4 > 7:5
