X = 2/3 + 5/6 + 4/6 + 5/6 = 9/6 = 3/2
When you simplify you are trying to see what the fraction is divisible by. You can do I faster if you know the fraction's greatest common factor.
Answer:
question 67-the answer is Rory has eaten 1 1/4 of all the chocolate he has been given.
question 68-answer A-30 degrees
Step-by-step explanation:
question 67:
first Rory ate 1/2 of his chocolate
then, his sister gave him another whole chocolate bar an hour later.
that is 1/2+1=1 1/2--3/2/2=3/4
add 3/4 and 1/2--3/4 1/2~2/4--2/4+3/4=5/4 or 1 1/4
so the answer is 1 1/4
question 68:
if you draw a base to connect the last side of the angle into a triangle, you find that all three sides are equal, making the triangle an equilateral triangle. An equilateral triangle's angles all equal 30 degrees.
so, the answer is answer A: 30 degrees
