Answer : D
Explanation
Step 1:
Weight of bulldozer = 3$\frac{2}{5}$ tons
Weight of sand = 5$\frac{5}{8}$ tons
Step 2:
Combined weight of bulldozer and sand
= 3$\frac{2}{5}$ tons + 5$\frac{5}{8}$ tons = $\frac{17}{5}$ + $\frac{45}{8}$
= $\frac{136}{40}$ + $\frac{225}{40}$ = $\frac{361}{40}$ = 9$\frac{1}{40}$ tons
Answer : A
Explanation
Step 1:
Size of regular bar = 7$\frac{3}{8}$ inches
king size bar longer by 5$\frac{3}{7}$ inches
Step 2:
Length of king size bar = 7$\frac{3}{8}$ inches + 5$\frac{3}{7}$ inches
= $\frac{59}{8}$ + $\frac{38}{7}$ = $\frac{413}{56}$ + $\frac{304}{56}$
= $\frac{717}{56}$ = 12$\frac{45}{56}$
Answer : B
Explanation
Step 1:
Boxes recycled in one month = 9$\frac{2}{3}$
Boxes recycled in second month = 6$\frac{4}{9}$
Step 2:
Total boxes recycled = 9$\frac{2}{3}$ + 6$\frac{4}{9}$
= $\frac{29}{3}$ + $\frac{58}{9}$ = $\frac{87}{9}$ + $\frac{58}{9}$
=$\frac{145}{9}$ = 16$\frac{1}{9}$
Answer : C
Explanation
Step 1:
Snowfall in November = 10$\frac{5}{8}$ inches
Snowfall in December = 5$\frac{6}{7}$ inches
Step 2:
Total snowfall in two months = 10$\frac{5}{8}$ + 5$\frac{6}{7}$
= $\frac{85}{8}$ + $\frac{41}{7}$ = $\frac{595}{56}$ + $\frac{328}{56}$
= $\frac{923}{56}$ = 16$\frac{27}{56}$ inches
Answer : A
Explanation
Step 1:
Length of first road = 6$\frac{2}{3}$ miles
Length of second road = 5$\frac{2}{5}$ miles
Step 2:
Total length roads = 6$\frac{2}{3}$ + 5$\frac{2}{5}$
= $\frac{20}{3}$ + $\frac{27}{5}$ = $\frac{100}{15}$ + $\frac{81}{15}$
= $\frac{181}{15}$ = 12$\frac{1}{15}$ miles
Answer : C
Explanation
Step 1:
Distance jogged on Tuesday = 5$\frac{2}{3}$ km
Distance jogged on Wednesday = 4$\frac{2}{9}$ km
Step 2:
Total distance jogged = 5$\frac{2}{3}$ + 4$\frac{2}{9}$
= $\frac{17}{3}$ + $\frac{38}{9}$ = $\frac{51}{9}$ + $\frac{38}{9}$
= $\frac{89}{9}$ = 9$\frac{8}{9}$ km
Answer : D
Explanation
Step 1:
Total time spent in studying = 5$\frac{3}{5}$ hours
Time spent on Saturday studying = 2$\frac{2}{3}$ hours
Step 2:
Time spent on Sunday studying = 5$\frac{3}{5}$ - 2$\frac{2}{3}$
= $\frac{28}{5}$ - $\frac{8}{3}$ = $\frac{84}{15}$ - $\frac{40}{15}$
= $\frac{44}{15}$ = 2$\frac{14}{15}$ hours
Answer : B
Explanation
Step 1:
Weight of potatoes first bought = 4$\frac{3}{7}$ pounds
Weight of potatoes bought later = 7$\frac{2}{5}$ pounds
Step 2:
Total boxes recycled = 4$\frac{3}{7}$ + 7$\frac{2}{5}$
= $\frac{31}{7}$ + $\frac{37}{5}$ = $\frac{155}{35}$ + $\frac{259}{35}$
=$\frac{414}{35}$ = 11$\frac{29}{35}$
Answer : C
Explanation
Step 1:
Height of sand castle = 4$\frac{2}{3}$ feet
Height of flag = 2$\frac{1}{6}$ feet
Step 2:
Total height = 4$\frac{2}{3}$ + 2$\frac{1}{6}$
= $\frac{14}{3}$ + $\frac{13}{6}$ = $\frac{28}{6}$ + $\frac{13}{6}$
= $\frac{41}{6}$ = 6$\frac{5}{6}$ feet
Answer : A
Explanation
Step 1:
Total distance walked = 4$\frac{4}{7}$ miles
Distance walked in the morning = 2$\frac{2}{5}$
Step 2:
Distance walked in the afternoon = 4$\frac{4}{7}$ - 2$\frac{2}{5}$
= $\frac{32}{7}$ - $\frac{12}{5}$ = $\frac{160}{35}$ - $\frac{84}{35}$
= $\frac{76}{35}$ = 2$\frac{6}{35}$ miles
