Let’s go through each pair of decimal numbers and compare them carefully. We’ll look at the digits from left to right — first the whole number part, then the tenths place, then the hundredths place if needed.
We are comparing decimals up to hundredths (two places after the decimal point), but some have dollars or more digits — we still compare digit by digit.
---
a. .45 ___ .66
→ Both start with 0 before the decimal.
→ Tenths: 4 vs 6 → 4 < 6 → So
.45 < .66
b. .11 ___ .80
→ Tenths: 1 vs 8 → 1 < 8 →
.11 < .80
c. .21 ___ .23
→ Same tenths (2). Hundredths: 1 vs 3 → 1 < 3 →
.21 < .23
d. .5 ___ .6
→ Think of as .50 and .60 → 50 < 60 →
.5 < .6
e. .1 ___ .8
→ .10 vs .80 → 10 < 80 →
.1 < .8
f. .2 ___ .4
→ .20 vs .40 → 20 < 40 →
.2 < .4
g. 1.3 ___ 2.1
→ Whole numbers: 1 vs 2 → 1 < 2 →
1.3 < 2.1
h. 3.4 ___ 3.6
→ Same whole number (3). Tenths: 4 vs 6 → 4 < 6 →
3.4 < 3.6
i. 1.7 ___ 1.7
→ Exactly the same →
1.7 = 1.7
j. 5.11 ___ 3.10
→ Whole numbers: 5 vs 3 → 5 > 3 →
5.11 > 3.10
k. 9.00 ___ 7.99
→ 9 > 7 →
9.00 > 7.99
l. 8.01 ___ 8.10
→ Same whole number (8). Tenths: 0 vs 1 → 0 < 1 →
8.01 < 8.10
m. 1.11 ___ 1.01
→ Same whole number (1). Tenths: 1 vs 0 → 1 > 0 →
1.11 > 1.01
n. 5.50 ___ 5.49
→ Same whole number (5). Tenths: 5 vs 4 → 5 > 4 →
5.50 > 5.49
o. 9.31 ___ 9.31
→ Identical →
9.31 = 9.31
p. 2.13 ___ 3.89
→ 2 < 3 →
2.13 < 3.89
q. 2.00 ___ 0.99
→ 2 > 0 →
2.00 > 0.99
r. 1.46 ___ 1.64
→ Same whole number (1). Tenths: 4 vs 6 → 4 < 6 →
1.46 < 1.64
s. .02 ___ .20
→ .02 is 2 hundredths, .20 is 20 hundredths → 2 < 20 →
.02 < .20
t. 8.99 ___ 7.23
→ 8 > 7 →
8.99 > 7.23
u. 6.10 ___ 5.85
→ 6 > 5 →
6.10 > 5.85
v. $1.25 ___ $1.52
→ Same dollar amount ($1). Cents: 25 vs 52 → 25 < 52 →
$1.25 < $1.52
w. $3.00 ___ $2.76
→ 3 > 2 →
$3.00 > $2.76
x. $0.87 ___ $0.63
→ Same dollars (0). Cents: 87 vs 63 → 87 > 63 →
$0.87 > $0.63
y. $1,451.02 ___ $1,541.02
→ Compare thousands: both 1 thousand. Hundreds: 4 vs 5 → 4 < 5 →
$1,451.02 < $1,541.02
z. $3,561.62 ___ $3,461.99
→ Thousands: both 3. Hundreds: 5 vs 4 → 5 > 4 →
$3,561.62 > $3,461.99
