Answer:

96 tiles

Step-by-step explanation:

The number of tiles measured  14 cm and 9 cm that will fit into a rectangular

region whose length and breadth are 168 cm and 72 cm may be computed as a ratio of the areas of the two rectangles.

Hence number of tiles

= 168 * 72/14 * 9

= 12 * 8

= 96 tiles

X : 14= 7: 8<br> can someone solve this for me and explain me
Vanyuwa [196]

x:14 = 7:8

x:14 = x/14

7:8 = 7/8

x/14 = 7/8

Multiply the numerator of the 1st ratio with the denominator of the 2nd.

And multiply the numerator of the 2nd ratio with the denominator of the 1st.

Doing so, we get -

x * 8 = 7 * 14

So, 8x = 7 * 14

8x = 98

We divide 98 by 8 (transposition method)

x = 98/8

Therefore, x = 12.25
