Answer:
3/12 = divide 3 to get the lowest number possible (In this case 1, so 3 divided by 3) and then divide the bigger number by same amount you've divided the smaller number (12 divided by 3 is 4, because 4 x 3 = 12). So our answer is 1/4. I'm too lazy to go in depth, but basically, 3 (4 times) is 12, so 3 takes up 1/4th of 12.

Answer:
10) 1/11
11) 18/8 or 2 2/8 or 2 1/4
12) -8/5 or -1 3/5
Step-by-step explanation:
10) -6/11-(-5/11)=-6/11+(5/11)=<em>1/11</em>
11) 1 3/8-(-7/8)=11/8+7/8=18/8 or 2 2/8 or 2 1/4
12) -4/5-4/5=-8/5 or -1 3/5

Answer:
The heigh of the triangle is 10cm
Step-by-step explanation:
The area of a triangle is given by the formula A=1/2bh where
A = the area of the triangle,
b = the length of the base, and
h = the height of the triangle.
To find the height when
the
Area of the triangle, A =45cm2,
base of the triangle, = 9 cm long.
Using the formula, A = 1/2 × b × h
45 = 1/2 × 9 × h
Cross multiplying
2×45 = 1×9×h
90 = 9h
h = 90/9 = 10cm
