Using the tip, what is the correct answer to the given calculation?
TIP: To multiply a number by 5: first divide by 2, then move the decimal point (d.p.) to the right. Note: whole numbers that do not have decimal parts are written without a d.p. e.g. 200.0 = 200: in such cases the d.p. is not normally needed. 3,434 × 5 = ?

Using the tip, what is the correct answer to the given calculation?
TIP: To divide a number by another number which is a multiple of 10 and whose only non zero digit is the leading digit 1: move the decimal point (d.p.) to the left by the same number of zeros that are in the multiple of 10. Note: whole numbers that do not have decimal parts are written without a d.p. e.g. 200.0 = 200: in such cases the d.p. is not normally needed. 76,345 ÷ 1,000 = ?
