QUESTION 1
7 pt 1c + 4pt 1c (pt for Pints; c for Cups)
= 7pt + 1c + 4pt + 1c
Collecting like terms
= 7pt + 4pt + 1c + 1c
= 11pt + 2c
1pt = 2c
Therefore,
11pt 2c = 11pt + 1pt
= 12 pt (OPTION B)
QUESTION 2
7c 3fl oz – 3c 4fl oz (c for Cups; oz for Ounce)
= 7c + 3fl oz – (3c + 4fl oz)
= 7c + 3fl oz – 3c – 4fl oz
Collecting like terms
= 7c – 3c + 3fl oz – 4fl oz
= 4c – 1fl oz
1c = 8fl oz
Therefore, 4c can be rewritten as 3c + 8fl oz
4c – 1fl oz = 3c +
8fl oz – 1fl oz
= 3c + 7fl oz
= 3c 7fl oz (Option B)
QUESTION 3
4lb 4oz – 2lb 7oz (lb for Pounds; oz for Ounce)
= 4lb + 4oz – (2lb + 7oz)
= 4lb + 4oz – 2lb – 7oz
Collecting like terms
= 4lb – 2lb + 4oz – 7oz
= 2lb – 3oz
1lb = 16oz
Therefore, 2lb can be rewritten as 1lb + 16oz
2lb – 3oz = 1lb + 16oz – 3oz
= 1lb + 13oz
= 1lb 13oz (Option A)
QUESTION 4
7T 200lb – 2T 700lb (T for Tons; lb for Pounds)
= 7T + 200lb – (2T + 700lb)
= 7T + 200lb – 2T – 700lb
Collecting like terms
= 7T – 2T + 200lb – 700lb
= 5T – 500lb
1T = 2,000lb
Therefore, 5T can be rewritten as 4T + 2,000lb
5T – 500lb = 4T + 2,000lb – 500lb]
= 4T + 1,500lb
= 4T 1,500lb (Option C)
QUESTION 5
7 d 12 h – 5 d 18 h (d for Days; h for Hours)
= 7d + 12h – (5d + 18h)
= 7d + 12h – 5d – 18h
Collecting like terms
= 7d – 5d + 12h – 18h
= 2d – 6h
1d = 24h
Therefore, 2d can be rewritten as 1d + 24h
2d – 6h = 1d + 24h – 6h
= 1d + 18h
= 1d 18h (Option B)
QUESTION 6
3 h 42 min – 1 h 12 min (h for Hours; min for Minutes)
= 3h + 42min – (1h + 12min)
= 3h + 42min – 1h – 12min
Collecting like terms
3h – 1h + 42min – 12min
= 2h + 30min
= 2h 30min (Option A)
