Question 3.
Check each sentence that is true.
 a. 35 is the same as 1 ten 25 ones.
 b. 28 is the same as 1 ten 18 ones.
 c. 36 is the same as 2 tens 16 ones.
 d. 39 is the same as 2 tens 29 ones.
Answer: option a, b, c are correct

Explanation:
a. 35 is the same as 1 ten 25 ones.
35 = 1 × 10 + 25 × 1
10 + 25 = 35
b. 28 is the same as 1 ten 18 ones.
28 = 1 × 10 + 18 × 1
= 10 + 18 = 28
c. 36 is the same as 2 tens 16 ones.
36 = 2 × 10 + 16 × 1
= 20 + 16 = 36
d. 39 is the same as 2 tens 29 ones.
39 = 2 × 10 + 29 × 1
= 20 + 29 = 49
Thus option d is not correct.

Question 4.
Emi says that 37 is the same as 1 ten 27 ones, and Ben says that 37 is the same as 2 tens 7 ones. Draw quick tens to show if Emi or Ben is correct.
Answer:

37 = 1 × 10 + 27 × 1
= 10 + 27 = 37
Ben says that 37 is the same as 2 tens 7 ones.
37 = 2 × 10 + 7 × 1
= 20 + 7 = 27
Emi is correct.
