Ellena knows that 1/5 written as a decimal is 0.2. How can Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5?
The decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5
How to convert from decimal to fraction?For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.
WE are given that Ellena knows that 1/5 written as a decimal is 0.2.
Thus Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5
By multiplying 0.2 by 9 we can get the decimal equivalent of 9/5.
0.2 x 9 = 4.5
Hence, the decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5

Answer:
1. J=20, f= 28, H=42
2. 240 + 241 + 242 = 723
Step-by-step explanation:
J= 30- 12= 18+2= 20
F= 30-2=28
H=30+12=42

240 + 241 + 242 = 723
Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!
Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
