Question

The number of stickers that Jane has is represented below. Jane has 17 fewer stickers than those with Jax. How many stickers does Jax have? Also calculate the total number of stickers they have in total.

• A. 91; 100
• B. 30; 72
• C. 59; 101
• D. 59; 91

Answer 1

The correct option is C 59; 101

There are 4 rods and 2 units = 4 tens and 2 ones = 42
Therefore, Jane has 42 stickers.

Let’s add 42 and 17.
After breakdown, we get
$\Rightarrow$ 42 = 40 + 2
$\Rightarrow$ 17 = 10 + 7.
Adding ones will give us: 2 + 7 = 9.
Adding tens will give us: 40 + 10 = 50.
After regrouping and adding the tens and ones, we get
$\Rightarrow$ 50 + 9 = 59


So, 42 + 17 = 59. Therefore, Jax has 59 stickers.

Let’s add 59 and 42.
After breakdown, we get
$\Rightarrow$ 59 = 50 + 9.
$\Rightarrow$ 42 = 40 + 2
Adding ones will give us: 9 + 2 = 11
Adding tens will give us: 50 + 40 = 90
After regrouping and adding the tens and ones, we get
$\Rightarrow$ 90 + 11 = 90 + 10 + 1 = 100 + 1 = 101


So, 59 + 42 = 101. Therefore, they both have 101 stickers in total.
