We need to find the number of scarves can she make if she needs 5/6 of a yard for each scarf.

Hence, she can make 8 scarves.
The rule for rounding is that if the fraction is less than 1/2, we round down; and if the fraction is more than 1/2, we round up.
Because 5/6 is a greater fraction than 1/2, we must round the existing whole number (8), up.
8 5/6 rounded to the nearest whole number is 9.
Hi there! You are subtracting a negative number, which is basically the same thing as adding, because two negatives make a positive. B and C is out, because they do not fit the expression. You are actually adding both numbers and anytime you have to subtract a negative number, you add. When you do basic math, 4 + 7 is 11. Both numbers are negative and D does not work, because you're adding from a negative number. The only answer choice that has the expression is A. The answer is A.
