3.7 · 37 / 10 = 3.7, with 3 ones and 7 tenths.
3 · 30 / 10 = 3. Each digit shifts one place right.
3.7 · Dividing by 10 shifts each digit one place right: 37 becomes 3.7.
True · That is exactly what dividing by 10 does to every digit in the number.
0.56 · 56 / 100 = 0.56.
Hundredths · Dividing by 100 shifts the 4 two places right, into the hundredths place.
0.04 · 4 / 100 = 0.04, with 4 hundredths.
True · Lena is right: two shifts right land the 4 in hundredths.
He shifted the digits two places, like dividing by 100 · Dividing by 10 only shifts one place. 26 ÷ 10 = 2.6, not 2.06.
25 · 250 / 10 = 25. 2.5 is two shifts and 2500 multiplies.
