Question
How much smaller is 2ab + 4b – c than 5ab – 3b + 2c
Solution
To find the answer we have to find the difference.
Here greater number 5ab – 3ab + 2c.
∴ Difference = 5ab – 3b + 2c – (2ab + 4b – c)
= 5ab – 3b + 2c + (– 2ab – 4b + c)
= 5ab – 3b + 2c – 2ab – 4b + c
= (5 – 2)ab + (– 3 – 4)b + (2 + 1)c
= 3ab + (– 7)b + 3c
= 3ab – 7b + 3c
It is 3ab – 7b + 3c smaller.
