N.1Fill in the missing number. 1 ft = 12 in, 1 yd = 3 ft, 1 lb = 16 oz, 1 gal = 4 qt, 1 qt = 2 pt, 1 pt = 2 c.

1. 1
   $8\text{ c}=$ $\boxed{}\text{ pt}$
2. 2
   $4\text{ gal}=$ $\boxed{}\text{ pt}$
3. 3
   $4\text{ qt}=$ $\boxed{}\text{ pt}$
4. 4
   $36\text{ c}=$ $\boxed{}\text{ qt}$

N.2Add or subtract. Regroup when you need to.

1. 5
   $9\text{ lb}12\text{ oz}+1\text{ lb}15\text{ oz}=$ $\boxed{}\text{ lb}\boxed{}\text{ oz}$
2. 6
   $2\text{ yd}1\text{ ft}+3\text{ yd}1\text{ ft}=$ $\boxed{}\text{ yd}\boxed{}\text{ ft}$
3. 7
   $1\text{ ft}5\text{ in}+6\text{ ft}10\text{ in}=$ $\boxed{}\text{ ft}\boxed{}\text{ in}$
4. 8
   $6\text{ gal}1\text{ qt}-4\text{ gal}3\text{ qt}=$ $\boxed{}\text{ gal}\boxed{}\text{ qt}$

N.3Fill in each box. 1 km = 1,000 m · 1 m = 100 cm · 1 cm = 10 mm · 1 kg = 1,000 g · 1 L = 1,000 mL

1. 9
   $2.5\text{ m}=$ $\boxed{}\text{ mm}$
2. 10
   $2.8\text{ cm}=$ $\boxed{}\text{ mm}$
3. 11
   $0.74\text{ kg}=$ $\boxed{}\text{ g}$
4. 12
   $1.4\text{ kg}=$ $\boxed{}\text{ g}$

N.4Use 1 in = 2.54 cm, 1 mi ≈ 1.61 km, 1 kg ≈ 2.2 lb and 1 gal ≈ 3.79 L. Round to the nearest tenth.

1. 13
   $25\text{ L}\approx \boxed{}\text{ gal}$
2. 14
   $39\text{ cm}\approx \boxed{}\text{ in}$
3. 15
   $54\text{ lb}\approx \boxed{}\text{ kg}$
4. 16
   $26\text{ mi}\approx \boxed{}\text{ km}$

N.5Use F = 1.8C + 32 and C = (F − 32) ÷ 1.8. Round to the nearest tenth if needed.

1. 17
   $90^{\circ }\text{C}=$ ${\boxed{}}^{\circ }\text{F}$
2. 18
   $149^{\circ }\text{F}=$ ${\boxed{}}^{\circ }\text{C}$
3. 19
   $-4^{\circ }\text{F}=$ ${\boxed{}}^{\circ }\text{C}$
4. 20
   $68^{\circ }\text{F}=$ ${\boxed{}}^{\circ }\text{C}$
