Answer:
a is the answer because it will be the right answer
Answer:
Step-by-step explanation:
The fraction form of 40 minutes is 2/3 of an hour.The fraction 27/75 is equivalent to (b) 9/25.If 18/54 = 6/m, then the value of m is 3.The fraction form of 0.08 is 8/100.The length of the other piece of wire is 8/7 - 4/7 = 4/7 m.0.5 is equivalent to 1/2, 2.004 is equivalent to 2004/1000, 1.75 is equivalent to 7/4, and 1.25 is equivalent to 5/4.3/4 is equivalent to 0.75, 3/40 is equivalent to 0.075, 1/125 is equivalent to 0.008, and 11/55 is equivalent to 0.2.(9/7 + 3/14) - (4/7 + 12/21) = (63/14 + 9/14) - (28/21 + 48/21) = 72/14 - 76/21 = 8/7 - 19/21 = 16/21.(i) 1/2 - 3/14 = 1/2 - 3/14 = 8/14 - 3/14 = 5/14. (ii) 3/10 - (3/5 - 1/2) = 3/10 - 3/5 + 1/2 = 3/10 - 6/10 + 5/10 = -2/10 + 5/10 = 3/10. (iii) 9/11 + 1/2 - 1/2 = 9/11 + 0 = 9/11.(i) 3/14 = 3/14. (ii) 3/5 - 1/2 = 6/10 - 5/10 = 1/10. (iii) 3/10 + 1/2 = 3/10 + 5/10 = 8/10.(i) 20 + 7 + 5/10 + 4/100 = 20 + 0.7 + 0.04 = 20.74. (ii) 3100 + 210 + 1 + 7/1000 = 300 + 20 + 1 + 0.007 = 321.007.
