Answer:
1 1/9
Step-by-step explanation:
You need to find a common denominator.
18 So, you need to make the fractions have the common denominator.
4/9=8/18 4/6=12/18
8+12+20
Thus, 4/9+4/6=20/18
20/18 simplified is 10/9
We need to make 10/9 into a mixed number.
10/9=1 1/9
Hope this helps!
Answer:
40. x = 106 degrees
41. x = 118 degrees
Step-by-step explanation:
40.
straight line has 180 degrees
180 - 128 = 52 : angle inside triangle
180 - 126 = 54 : angle inside triangle
52 + 54 = 106
triangle has 180 degrees
180 - 106 = 74 : 3rd angle inside the triangle
again straight line has 180 degrees
180 - 74 = 106 = x
41.
shape of 4 sides is 360 degrees
180 - 34 = 146
little box means one the sides is 90 degrees on either side
146 + 90 = 236
360 - 236 = 124
both x's are the same so angles inside are the same too
124 ÷ 2 = 62
straight line is 180
180 - 62 = 118
x = 118
Answer:
A
Step-by-step explanation:
For Q1, we can start out by turning it into a plain fraction. 16*2=32, and 32+1=33, so 16+1/2=33/2. Similarly, for 2 3/4, 2*4=8 and 8+3=11, so 2 3/4=11/4 as the size of each piece of wood. To divide them, we have the numbers 33/2 and 11/4. We first find the reciprocal of the size of a piece (switch the numerator and denominator) and then multiply the 2 fractions - 33/2*4/11=132/22=6 pieces. Using that, I challenge you to do Q2 on your own!
