Write the product as the product of a whole number and a unit fraction 2x4\5=

2 × 4 = 8 ÷ 5 = 1.6 = 1 3/5

i think the question is 2 × 4/5 = 1.6 it is easy because 4/5 you making double like 4/5 + 4/5 = 1 3/5                                                                            0.80 + 0.80 = 1.60
