Express 240g as a percentage of 2.5kg​

0.1%

Step-by-step explanation:

Given that 240 g of 2.5 kg

We have to express this in percentage

But we know that 1 kg = 1000 g, So first convert 2.5 kg to g

2.5 kg = 2.5 x 1000 g = 2500 g

The formula of "a" % of "b" is given as:

× 100

Hence, 240 g as a percentage of 2500 g is given as:

×

= = 0.1

Thus, the answer is 0.1 %

maybe - definition of supplementary angles. im not sure. sorry

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
