7 1/8 = 57/8
57 divide by 6= 9.5
So you would have 9 1/2
Answer:
0.86 hour
Step-by-step explanation:
Jess jogs at a rate of 6 miles per hour.
The next time she jogs she increases her speed to a rate of 7 mile per hour.
The new rate of Jess's jogging is 7 miles per hour
How long will it take her to jog 6 miles?
Hence:
7 miles = 1 hour
6 miles = x hours
Cross Multiply
7 × x = 6 × 1
x = 6/7
x = 0.8571428571 hour
Approximately = 0.86 hour
It will take Jess 0.86 hour to jog for 6 miles
Answer:
Step-by-step explanation:
x 6 a
8 48 c
-4 b 20
Let the unknown numbers of the multiplication grid are a, b and c.
1). 6 × 8 = 48
2). (-4)×6 = b
b = -24
3). (-4) × a = 20
a = -5
4). 8 × a = c
8 × (-5) = c
c = -40
Therefore, missing in the given multiplication grid are,
x 6 -5
8 48 -40
-4 -24 20
Answer:
2
Step-by-step explanation:
this is the correct answer
Answer:
5/6
Step-by-step explanation:
9/18 + 1/3 <Need the same denominator so find the lowest common multiple.
3 6 9 12 15 18 < multiples of 3
if 3 goes into 18 than it will be our LCM
3 goes into 18 6 times so multiply 1 and 3 by 6 and rewrite the equation
9/18 + 6/18 < just add 9 + 6 and place it over 18
15/18 <this number can be simplified so write out their factors and pick the highest one to divide by one they have in common.
1 3 5 15 <Factors of 15
1 2 3 6 9 18 <Factors of 18
3 is the highest one they both have so divide both 15 and 18 by 3
15/3 is 5 and 18/3 is 6
put the 5 and 6 in their proper places and you have 5/6 or .83333333333...
