Question

A box of Shredded Wheat weighs 0.35 kg and a box of Weetabix weighs 9/25 kg? Which box is heavier?

Answer 1

Answer:

The box of Weetabix is heavier by 0.01 kg

Step-by-step explanation:

Divide 9/25 to get the decimal equivalent

9÷25 =0.36

Compare Shredded Wheat at 0.35 kg to Weetabix at 0.36 kg

Answer 2

Given,

Box of shredded wheat weighs = 0.35 kg

Box of weetabix weighs = 9/25 kg

To find,

The box which is heavier.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now,

We will convert the weight of the box of shredded wheat, into fractional form to compare it with the weight of the weight of the box of weetabix.

So,

Weight of the box of shredded wheat :

= 0.35 kg

= 35/100 kg

= 7/20 kg

Now, comparing the fractions 9/25 and 7/20 :

Equating them,

LCM of denominators (25,20) = 100

So,

First fraction can be written as = (9×4)/(25×4) = 36/100

Second fraction can be written as = (7×5)/(20×5) = 35/100

(In both rewritten forms, a number is multiplied with both the numerator and the denominator to equate the final denominators with the previously obtained LCM)

Now, it is obvious that,

36/100 > 35/100

Or, 9/25 > 7/20

Or, 9/25 > 35/100

Or, 9/25 > 0.35

Thus,

Weight of weetabix box > Weight of shredded wheat box

Hence, box of shredded wheat is heavier.
