If a scale of 2cm represent 3/4km find the length on the scale drawing in 30km

2/(3/4) = x/30

2/(3/4) = x/30

Cross multiply and solve for x.

If a scale of 2cm represents 3/4km, find the length on the scale drawing with an actual length of 30km.

If 2cm represent 3/4then what is the answer

To find the length on the scale drawing with an actual length of 30 km:

We can use the proportion:

2 cm / (3/4) km = x cm / 30 km

First, we need to convert 3/4 km to cm:

(3/4) km = (3/4) x 100000 cm/km = 75000 cm

Now we can substitute the values into the proportion:

2 cm / 75000 cm = x cm / 30000 cm

Cross-multiplying:

2 cm x 30000 cm = 75000 cm x x cm

60000 cm = 75000 cm x

x = 60000 cm / 75000 cm

x = 0.8 cm

Therefore, the length on the scale drawing with an actual length of 30 km is 0.8 cm.

Well, if a scale of 2cm represents 3/4km, then to find the length on the scale drawing for 30km, we need to do some math.

Since 3/4km is represented by 2cm on the scale drawing, we can set up a proportion to find out how many centimeters would represent 30km.

(2cm / (3/4km)) = (x cm / 30km)

To solve this, we can cross-multiply:

2cm * 30km = (3/4km) * x cm

60cm * km = (3/4km) * x cm

Now, let's simplify:

60 = (3/4) * x

To find the value of x, we can multiply both sides by 4 and then divide by 3:

(4/3) * 60 = x

So, on the scale drawing, 30km would be represented by approximately 80cm.

But hey, don't get too carried away with the scale drawing. Remember, in real life, 30km is actually a lot longer than that!

To find the length on the scale drawing for 30km, you need to use the scale of 2cm to represent 3/4km.

First, calculate the length represented by 1km on the scale drawing:
- Since 2cm represents 3/4km, we need to divide 3/4 by 2 to find the length represented by 1cm.
- 3/4 ÷ 2 = 3/8 km.

Now that we know that 1cm represents 3/8km, we can find the length on the scale drawing for 30km by multiplying the length represented by 1cm by 30:
- (3/8 km) * 30 = (3 * 30) / 8 = 90/8 km.

Therefore, the length on the scale drawing for 30km is 90/8 km, or approximately 11.25 km.
