Find the product: (i) 73.92 x 10 (ii) 7.54 x 10 (iii) 84.003 x 10 (iv) 2.397 x 100 (v) 6.83 x 100 (vi) 2.9 x 100 (vii) 6.7314 x 1000 (viii) 0.182 x 1000 (ix) 0.076 x 1000

Here are the solutions to the problems.

1. Find the product:

• (i) To multiply 73.92 by 10, move the decimal point one place to the right.

  $$73.92 \times 10 = 739.2$$ $$\boxed{\text{739.2}}$$

• (ii) To multiply 7.54 by 10, move the decimal point one place to the right.

  $$7.54 \times 10 = 75.4$$ $$\boxed{\text{75.4}}$$

• (iii) To multiply 84.003 by 10, move the decimal point one place to the right.

  $$84.003 \times 10 = 840.03$$ $$\boxed{\text{840.03}}$$

• (iv) To multiply 2.397 by 100, move the decimal point two places to the right.

  $$2.397 \times 100 = 239.7$$ $$\boxed{\text{239.7}}$$

• (v) To multiply 6.83 by 100, move the decimal point two places to the right.

  $$6.83 \times 100 = 683$$ $$\boxed{\text{683}}$$

• (vi) To multiply 2.9 by 100, move the decimal point two places to the right, adding a zero.

  $$2.9 \times 100 = 290$$ $$\boxed{\text{290}}$$

• (vii) To multiply 6.7314 by 1000, move the decimal point three places to the right.

  $$6.7314 \times 1000 = 6731.4$$ $$\boxed{\text{6731.4}}$$

• (viii) To multiply 0.182 by 1000, move the decimal point three places to the right.

  $$0.182 \times 1000 = 182$$ $$\boxed{\text{182}}$$

• (ix) To multiply 0.076 by 1000, move the decimal point three places to the right.

  $$0.076 \times 1000 = 76$$ $$\boxed{\text{76}}$$
