j. 11 5/12
k. 1 5/12
l. 13 7/9
Step-by-step explanation:
Hello! The step by step solution is to simply add them together. Let's take a. 7 3/8 + 3 1/4 for an example. Change the denominator (the bottom number of the fraction) into something both can go into. 4 can go into 8 and 8 can go into 8. Rewrite the fractions beside the actual numbers. Example: /8 and /8 then remember, 4 goes into 8 two times. So do 1x2=2. Then remember 8 goes into 8 1 time so do 3x1=3. Add the two fractions 3/8+2/8= 5/8. Then add the whole numbers as well. 7+3+5/8= 10 5/8. I know that it's really confusing explaining it through words but if you ever need further explanation don't hesitate to ask! :)
Answer: she had 18 nickels and 7 dimes.
Step-by-step explanation:
The worth of a dime is 10 cents. Converting to dollars, it becomes
10/100 = $0.1
The worth of a nickel is 5 cents. Converting to dollars, it becomes
5/100 = $0.05
Let x represent the number of dimes that she has in her coin purse.
Let y represent the number of nickels that she has in her coin purse.
Alison has 1.60 worth of nickels and dimes in her coin purse. This means that
0.1x + 0.05y = 1.6 - - - - - - - - - - - 1
She has 11 more nickels than dimes. It means that
y = x + 11
Substituting y = x + 11 into equation 1, it becomes
0.1x + 0.05(x + 11) = 1.6
0.1x + 0.05x + 0.55 = 1.6
0.15x = 1.05
x = 1.05/0.15
x = 7
y = x + 11 = 7 + 11
y = 18
False, its false................
