What is 1 7/8 • 5/6<br> And 2 1/3 • 5/16
m_a_m_a [10]

Answer:

55/24

Step-by-step explanation:

First, multiply 1 7/8 by 5/6, obtaining 15/8 times 5/6, or 75/48.

Next, multiply 2 1/3 by 5/16.  This is equivalent to multiplying 7/3 by 5/16, and the result of this multiplication is 35/48.

Now combine 75/48 and 35/48, obtaining 110/48, or 55/24.

Predict: How do you think the formula for area of a triangle will relate to the formula for area of a rectangle? Do you
densk [106]

Answer:

I think is the same formula area .A triangle is half as big as the rectangle that surrounds it, which is why the area of a triangle is one-half base times height.

Step-by-step explanation:

The area of a rectangle is given by the relation length* width. The area of a triangle is given by the relation (1/2)*base* height. Now we know that the two have the same area equal to 150 cm^2. Also, when placed on the same level the tip of the triangle touches the upper edge of the rectangle.
