Answer:
6³/₁₀
Step-by-step explanation:
Number of bits = Total amount/Size of each bit
= (4⅕)/(⅔)
Convert the mixed number to an improper fraction
No. = (²¹/₅)/(⅔)
Invert the denominator and change division to multiplication
No. = ²¹/₅ × ³/₂
Multiply numerators and denominators.
No. = ⁶³/₁₀
Convert the improper fraction to a mixed number.
No. = 6³/₁₀
It takes 6³/₁₀ ⅔s to make up 4⅕.
Answer:
2 mph
Step-by-step explanation:
time = distance / speed
Let c represent the rate of the current. Then the upstream rate of the boat relative to the shore is (5c -c) = 4c, and the <em>upstream time</em> is ...
... 12/(4c) = 3/c.
Likewise, the downstream rate is (5c +c) = 6c, and the <em>downstream time</em> is ...
... 12/(6c) = 2/c.
The <em>total time</em> is the sum of upstream and downstream times:
... 3/c +2/c = 2.5
... 5/c = 2.5 . . . . . . combine terms
... 5/2.5 = c = 2 . . . multiply by c/2.5
11a) False. If you simplify 8/30 you get 4/15 not 2/15.
11b) False. If you simplify 6/15, you get 2/5 not 3/5.
11c) true. 5/15 can be simplified to 1/3.
Answer:
125 adults
175 children
Step-by-step explanation:
3900=8c+20a
300=c+a
c=300-a
substitute
3900=8(300-a)+20a
reduce
3900=2400-8a+20a
1500=12a
a=125 adults
substitute for a
c=300-a
c=300-125
c=175 children
