Explanation:
not all is really visible. so, I am not sure, if I miss any important answer option.
but in any case, all of these questions can be easily solved by simply using a calculator. the same thing I am doing now.
1kg beef costs 250.75
2.80kg cost ... well, 2.80 times the price of 1kg.
2.8×250.75 = Php 702.10
the area of a rectangle is simply the multiplication of length and width.
garden area = 7.5 × 3.02 = 22.65 m²
the beans cost 48.50 per kg.
how much is 0.5 or 1/2kg ?
it is the same principle as in the first question :
it costs half the price of a full kg.
48.50 / 2 = Php 24.25
the area of the rectangle is 24m².
it is the same principle as for the second question : length multiplied by width is the area.
so, the multiplications that are not creating 24 as result, are the answer.
A. is not a possible dimension for the room. although I cannot fully read it, but 24/3.4 = 7.0588...
that did not seem to match what is written there.
B. is correct. 2.4×10 is indeed 24.
C. is correct. 3 × 8 is indeed 24.
D. is correct. 7.5 × 3.2 is indeed 24.
