f. 20 + _____ = 40
g. 15 + _____ = 35
h. 2 tens + 1 ten 2 ones = _________________
Answer:
a. 30 + 6 = 36
Adding of 3 tens with 6 ones =36
b. 3 tens — 2tens = 1 ten
Removing 20 from 30 makes 10
30-20=10
c. 11 + 10 = 21
Adding 11 with 10
11+10=21
d. 40 — 30 =10
Removing 3 tens from 4 tens gives 1 tens
40-30=10
e. 17 + 20 =37
Adding 17 with 20 results in 37
f. 20 + 20 = 40
To make the equation equal to 40 add the given 20 with another 20
g. 15 +10= 35
To make the equation equal to35 add the given 15 with 10
h. 2 tens + 1 ten 2 ones =32
Adding 2 tens which 20 with 1 ten and 2 ones which is 12
20+12=32
