Carpet tiles are going to be used to cover floor the floor is a 1200mm by 1000mm rectangle each carpet tile is 40 cm by 30 cm rectangle exactly 10 carpet tiles can be used to cover the floor completely show in a labelled sketch as can be done

we know that

the rectangular floor measure 1200 mm x 1000 mm

each carpet tile measure is 40 cm by 30 cm-----> is equal to 400 mm x 300 mm

Divide

1200/400=3 carpet tile

1200/300=4 carpet tile

1000=400+300+300

therefore

the answer in the attached figure

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
