Hi!

When you add a negative number, you really just subtract it. So let's solve this.

Convert the mixed numbers into improper fractions.

\frac{434}{9} - \frac{351}{9}

Solve

434 - 351 = 83

\frac{83}{9}

The sign of this fraction is positive

Hope this helps! :)

Calculating area of rectangle
PSYCHO15rus [73]

Answer:

Area = 216.108cm^2 --- You

Area = 216.940cm^2 --- Another student

Reason: Because there is a variation in the given dimensions

Step-by-step explanation:

Given

Your measurement

Length = 20.70cm; Width =10.44cm

Another students'

Length = 20.74cm; Width =10.46cm

Solving (a): The area

Area is calculated as:

Area = Length * Width

For you

Area = 20.70cm * 10.44cm

Area = 216.108cm^2

For the other student

Area = 20.74cm * 10.46cm

Area = 216.940cm^2

Solving (b): Reason for the variation in the areas

The given measurements are estimates of the dimensions of the rectangle.

Since there is a variation in the estimates, there will be some level of variation in the calculated area.

ILL GIVE BRAINLIST ON WHOEVER GETS RIGHT!!!!
tiny-mole [99]

Answer:

The first and third answer I believe.

Step-by-step explanation:

The side with 3 can go over 1.5, since they are both at the same side. It will be equivalent to 4 over 2 because they are also the same side. (1st option)

Multiplying each side by 1/2, does result you to the final image.

3 multiplied by 1/2 is 1.5

4 multiplied by 2 is 2
