Question

54. Product of two numbers is 18.75. If one
number is three times the other, then larger
number is
1. 2.5
2. 3.5
3. 4.5
4. 7.5​

Answer 1

Explanation:

Let the smaller number be x. Then the greater number is 3x.

$(x)(3x)=18.75$

$3x^2=18.75$

$x^2=\frac{18.75}{3}=6.25$

$x=\sqrt{6.25} = 2.5$

Hence, the greater number is

$3x=3(2.5)=7.5$

Answer: 7.5

Answer 2

Answer:

(1) 2.5

Step-by-step explanation:

3x2=18.75 or x2=6.25 or x=root 6.25 = 2.5
