Answer/Step-by-step explanation:
2/5 + 1/3
5 times 3 is 15, so 2*3 and 1*5
6/15 + 5/15
6+5 = 11, and 11/15 cannot be simplified so:
11/15
Answer:
Step-by-step explanation:
decimal repeats without a pattern
This is the concept of application of quadratic equations; To get the number of dimes and quarters we proceed as follows;
suppose there are x dimes and y quarters;
x+y=95.......i
but we know;
$0.1=1 dimes
$0.25=1 quarters
thus
0.1x+0.25y=23.45.....ii
solving equation i and ii by substitution we shall have:
from i;
x=95-y
thus substituting the value of x in equation ii we get
0.1(95-y)+0.25y=23.45
9.5-0.1y+0.25y=23.45
collecting like terms we get:
0.15y=13.95
dividing both sides by 0.15 we get;
y=13.95/0.15=93
x=95-93=2
therefore we conclude that there were 2 dimes and 93 quarters
6/3=2
5.5x2 =11 scale factor is 2
