Please help me to solve this question
luda_lava [24]
The equation for area of a triangle is 0.5*base*height, so when you halve both the base and height, the area gets divided by 4.

The area of the first triangle is 0.5*80*40 = 1600 cm^2.

6 1/4 cm^2 is the same as 25/4 cm^2.

Now, we have to see how many times 1600 cm^2 can be divided by 4 to get 25/4 cm^2.

Area of second triangle: 1600/4 = 400
Area of third triangle: 400/4 = 100
Area of fourth triangle: 100/4 = 25
Area of fifth triangle = 25/4

So, the fifth triangle has an area of 6 1/4 cm^2.

The pattern would be the area of the nth triangle = \frac{1600}{4^{n-1}}

Which equation can be represented using the number line?
kvasek [131]

Answer:

the first one : 3/4 ÷ 1/8 = 6

Step-by-step explanation:

remember, dividing something by a fraction is the same as multiplying by the upside-down fraction.

like here

3/4 ÷ 1/8 = 3/4 × 8/1 = 3×8 / 4×1 = 24/4 = 6

you can see that confirmed in the graph, where every 1/4 contains 2/8. so, 1/8 fits 6 times into 3/4.

the other answer options are simply not true

1/8 ÷ 3/4 = 6

1/8 × 4/3 = 4/24 = 1/6 <> 6

6 ÷ 3/4 = 1/8

6/1 × 4/3 = 24/3 = 8 <> 1/8

6 ÷ 1/8 = 3/4

6/1 × 8/1 = 48 <> 3/4
