So k in the first problem would =1/2
and i guess in the second problem just put k in place of the first space and in the second space put 8 for x. y would then =4. Idk if I did this right, though, I'm honestly a little confused too.
Answer:
The first fraction is between 27 and 28, closer to 28. The second fraction is between 3 and 4, closer to 4. Compatible numbers in division are numbers that can be divided mentally. 28 divided by 4 is 7. The quotient will be around 7.

Answer:
3 1/4 + 2 1/3 = 67 / 12 = 57 1/2
Step-by-step explanation:
Conversion a mixed number to a improper fraction: 3 1/4 = 3 · 4 + 1
4
= 13
4
Conversion a mixed number to a improper fraction: 2 1/3 = 2 · 3 + 1
3
= 7
3
Add: 13
4
+ 7
3
= 13 · 3
4 · 3
+ 7 · 4
3 · 4
= 39
12
+ 28
12
= 39 + 28
12
= 67

One common example of perpendicular lines in real life is the point where two city roads intersect. When one road crosses another, the two streets join at right angles to each other and form a cross-type pattern. Perpendicular lines form 90-degree angles, or right angles, to each other on a two-dimensional plane<span>Other real-world examples of perpendicular lines include graph paper, plaid patterns on fabric, square lines of floor tiles, lines of mortar on brick walls, the intersecting lines of a Christian cross, metal rods on the cooking surface of a barbecue grill, wooden beams in the wall of a house, and the designs on country flags such as Norway, the United Kingdom, Switzerland, Greece, Denmark and Finland. Perpendicular lines form the corner of squares and rectangles in various real-world shapes.Perpendicular lines create four right angles at their intersection point, making 360 degrees total. Perpendicular lines also form one angle of a right triangle. Perpendicular lines are concepts taught in algebra and geometry as students learn to calculate slopes of lines on graph paper.</span><span>Parallel lines differ from perpendicular lines in that parallel lines never intersect. Real-world examples of parallel lines include railroad tracks, stripes on the American flag, power lines hung between poles, lines on composition paper and plugs at the end of electrical cords.</span>.
Answer:
15/24
Step-by-step explanation:
1) Change the mixed numbers into improper fractions: 15/8 and leave 1/3 alone.
2) Then multiply the numerators and denominators: 15/24
