Question

which is greater?

16 % of 420 or 18% of 450.

it answer is 18% of 450.

but anyone you can explain me step by step solution.​

Answer 1

Step-by-step explanation:

let take first 16% of 420

then it is 420×16/100

=67.2

now let take 18% of 450

then it is 450 ×18/100

= 81

so, we can say that 67.2<81

therefore 16% of 420 < 18% of 450

Answer 2

ANSWER:

SO,

FIRST WE WILL SOLVE 16% OF 420

16 % OF 420

16/100×420

16/10×42(WE CUT THE TWO ZERO OF 100 AND 420)

16/5×21(WE DIVIDE THE 2 WITH 10 AND 42)

3.2×21(DIVIDE 5 BY 16)

67.2(YOUR FIRST ANSWER)

NEXT WE WILL DO THE SECOND NUMBER

18% OF 450

18/100×450

18/10×45(BY CUTTING ZERO IN 100 AND 450)

18/2×9(BY DIVIDING 5 IN BOTH 10 AND 45)

9×9(BY DIVIDING 18 BY 2)

36(YOUR SECOND ANSWER)

THANKS.
