Answer 1

• 21 cards left

Explanation:

We know that:

• 72 - (Harrison + Alwine) = Cards left to sign
• Harison = 1/3 x 72
• Alwine = 3/8 x 72

Solution:

• 72 - {(1/3 x 72) + (3/8 x 72)} = Cards left to sign
• => 72 - {24 + 27} = Cards left to sign
• => 72 - {51} = Cards left to sign
• => 72 - 51 = Cards left to sign
• => 21 cards left

Hence, 21 cards are left when Harrison signs 1/3 of the cards and Alwine signs 3/8.

Answer 2

21 cards left to be signed

Explanation:

1/3 of 72 is 24

So Harrison signed 24

3/8 of 72 is 27

Sp Alwine signed 27

24+27=51

So 72-51=21

21 cards left to be signed
