Question

Q1 Two numbers are in the ratio 4:5
and their sum is 180. Find the
numbers.

Q2 If two-thirds of a number is 2 less
than 8, find the number.

Q3 The product of two numbers is -21/16 If one of them is -1/3 find the other.

Answer 1

Answer:

Step-by-step explanation:

1. Let ratio be 4x:5x

Sum = 180

4x + 5x = 180

9x = 180

x = 180/9

x = 20

4(x) = 4(20) = 80

5(x) = 5(20) = 100

2. Let the number be x

2/3x = 8 - 2

2/3x = 6

x = 6 x 3/2

x = 9

3. Let a number be y

Product = -21/16

y x -1/3 = -21/16

y = -21/16 x 3/-1

y = 63/16
