1.

How much smaller is 2ab + 4b – c than 5ab – 3b + 2c.

Answer»

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.
