Question

1--solve 2p+4=25

2--Define unlike fraction

3--Find a number such that one fourth of the number is more than 7​

Answer 1

2p+5=25

2p=25-5

2p=20

p=20\2

p=10

Answer 2

1) 2p + 4 = 25

=> 2p = 25 - 4

=> 2p = 21

=> p = 21 ÷ 2

=> p = 10.5

2) Unlike fractions are those fractions which do not have similar denominators. Examples:

$\frac{4}{5} \frac{8}{3} \frac{2}{9}$

The above fractions are unlike fractions.

3) Let the number be x.

According to the question,

$\frac{1}{4} x > 7$

We know that 7 × 4 = 28.

So, by assuming that x is more than 28, and the product of (7+1) and 4, we get, x = 8 × 4 = 32.

Therefore, x can be 32.

Actually, any number that is more than 28 will satisfy the rule.
