1 answer:

3 0

There is equation to solve.However I can give an example using inverse operations and then I will the solution.

28 = 7×
Find the value of x

The opposite operation of multiplication is division.Therefore I can divide 28÷ 7 and 7÷7
.You would cancel out the 7 so you would have x equals to 4.

To check my solution,I would substitute the x by 4 and rewrite the problem as 7 (4) and that is equivalent to 28.So the answer is x=4.

Hope this helps. =)

A 450m long field is drawn to a scale 1cm to 90cm.find the lenth of drawing

irina1246 [14]

Answer:

500cm or 5 meters

Step-by-step explanation:

The ratio of drawing and field is 1:90.

So we have to make 450 m into cm.

450 -> is 45,000

Now we can make 2 fractions,

$\frac{1}{90}=\frac{x}{45000}$

Cross multiply

90*x = 90x

1*45000 = 45000

90x = 45000

Divide 90 to both sides

x = 500cm

Thus,

the drawing's field is 500cm or 5m long.

Hope this helps :)
