Answer 1

Answer:

705/100 grams cann be covered by the basic postage

Step-by-step explanation:

Given

Basic Postage

$Weight < 7.5g$

Heavy letters

$Weight \ge 7.5g$

Required

Can $705/100$ be covered in basic postage?

We have:

$Weight = 705/100\ g$

$Weight = 7.05\ g$

By comparing the above with the range of basic postage ---- $Weight < 7.5g$

We have:

$7.05g < 7.5g$

Since the above inequality is true, then the letter can be covered
