Answer:
Quotient is 
and remainder is 0.
Step-by-step explanation:
Given:
Dividend = 
Divisor = 
The long division is shown in the attachment.
Step 1: we need to divide with we first multiply with 3x we get the remainder as 
Quotient as 3x.
Step 2: Now the dividend is and divisor now we will multiply with -5 we get the remainder as 0 and Quotient as
Hence Quotient is and remainder is 0.
You need to multiply 25 by 18 to find the total.
25 x 18 = 450.
There are 450 chocolate bars in the large box
Answer:
y divided by 6 1/4 = 11 3/4
Step-by-step explanation:
First, change the mixed numbers into improper fractions:
y divided by 25/4 = 47/4
Next, multiply both sides by 25/4:
y divided by 25/4 x 25/4 = 47/4 x 25/4
The 25/4's on the left side of the equation cancel each other out, leaving you with:
y = 47/4 x 25/4
Multiply 47 x 25 and keep the same denominator:
y = 1,175/4
Divide and:
y = 293 3/4
