First you have to convert the denominators to the Lowest Common Multiple (unless the denominators are equal, of course).
Example 1/4 + 1/2
The LCM of 2 and 4 = 4 so we can write 1/2 as 1*2/2*2 = 2/4.
Now we can add:-
1/4 + 2/4 = 3/4.
Same thing goes for subtraction.
Example 2:-
5/6 - 1/7 :-
LCM of 6 and 7 = 6*7 = 42 so we have:-
5*7 / 6*7 - 1*6 / 7*6
= 35/42 - 6/42 = 29/42
Answer:
1.052
Step-by-step explanation:
Add 1 to the percent increase.
1 + 5.2% = 1 + 5.2/100 = 1 + 0.052 = 1.052
Answer: 1.052
Step-by-step explanation:
Answer:
C. 20
Step-by-step explanation:
If 1 inch is 8 miles, 2.5 = 20 miles because 8 x 2 = 16 and .5 = 4 so 16+4 = 20
