Miran and Hanna were asked by their teachers to increase 70 by 150%. Miran says the answer is 105 because 50%of 70 is 35 and 70+35=105. Hanna says the answer is 175 because 150% of 70 is 105 and 70+105=175. Who is correct

Hanna

Step-by-step explanation:

When you find out the % of a number you turn the percentage into a decimal.

150%=1.5

Then you multiply by your original number.

70 x 1.5 = 105

Finally you add that to your original number.

105 + 70 = 175

Since Hanna said increasing 70 by 150% is 175, she is correct.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

is means division by fractions
