Lucy used 2 1/3 kilograms of apples for her dessert.
Get the whole fraction.
3 2/3 = ((3*3) + 2) / 3 = 11/3
1 1/3 = ((3*1) + 1) / 3 = 4/3
Original weight of apples = 11/3
Remaining weight of apples = 4/3
weight of apples used = ?
Subtracting fractions:
Step 1. Make sure the denominator are the same
11/3 - 4/3
Step 2. Subtract the numerators and put the difference above the denominator
(11 - 4) / 3 = 7/3
Step 3. Simplify the fraction
7/3 = 2 1/3
Answer:
70 clicks in 20 seconds
Step-by-step explanation:
The speed of the train in mile per hour is approximately the number of clicks heads in 20 seconds.
Each click shows that the train has travelled 30ft
1 click per second is =(30ft/sec = 3600 × 30) / 5280
20.45mph approximately 20mph
Therefore
20mph = 20 clicks in 20 s
30mph = 30 clicks in 20s
70mph= 70 clicks in 20s
