  The place value of 5 is 5 thousands or 5000 and its face value is 5 in 5432. Explanation: Given number: 5 4 3 2 The digit 2 is in ones place in the number 5432.So,the place value of 2 will be 2 ones or (2×1) which is 2. The digit 3 is in tens place in the number 5432.So, the place value of 3 will be 3 tens or (3×10) which is 30. The digit 4 is in hundreds place in the number 5432.So,the place value of 4 will be 4 hundreds or (4×100) which is 400. Besides,the digit 5 is in thousands place in the number 5432.So,the place value of 5 will be 5 thousands or (5×1000) which is 5000. Again,given number: 5432 The face value of 5 is 5.Besides, the face value of 4 is 4 , the face value of 3 is 3 and the face value of 2 is 2.In case of face value, you need to write the digit itself.

  30 Explanation: 100 divided by 3 1/3 =100 ÷ 3 1/3 (Translating) =100/1 ÷ 3 1/3(Transforming whole number as a fraction considering 1 as a denominator) =100/1 ÷ (3×3+1)/3 (Mixed fraction to improper fraction) =100/1 ÷ (10/3) =100/1 × 3/10(Change of division sign and multiplied by the reciprocal fraction) =(100×3)/(1×10) [Multiply top to top and bottom to bottom numbers) =(10×10×3)/(1×10) Now reduce by canceling the common factor 10 =(10×3)/1 =30/1 =30 The answer for 100 divided by 3 1/3   is 30.

   1/36 Explanation: 1/72 divided by 1/2 =1/72 ÷ 1/2 (Translating) =1/72 × 2/1(Change of division sign and multiplied by the reciprocal fraction) =(1×2)/(72×1) [Multiply top to top and bottom to bottom numbers) =(1×2)/(36×2) Now reduce by canceling the common factor 2 =1/36 The answer for 1/72 divided by 1/2   is 1/36.

   10 1/2 Explanation: 3/4 divided by 1/14 =3/4 ÷ 1/14 (Translating) =3/4 × 14/1(Change of division sign and multiplied by the reciprocal fraction) =(3×14)/(4×1) [Multiply top to top and bottom to bottom numbers) =(3×7×2)/(2×2×1) Now reduce by canceling the common factor =(3×7)/(2×1) 【Cancel 2 from both sides】 =21/2 =21/2 This is a improper fraction.We need to change it as a mixed fraction.  =10 1/2 The answer for 3/4 divided by 21/2   is 10 1/2.

  24 Explanation: 3/4 divided by 1/32 =3/4 ÷ 1/32 (Translating) =3/4 × 32/1(Change of division sign and multiplied by the reciprocal fraction) =(3×32)/(4×1) [Multiply top to top and bottom to bottom numbers) =(3×8×4)/(4×1) Now reduce by canceling the common factor =(3×8×4)/(4×1)

  12 Explanation: 3/4 divided by 1/16 =3/4 ÷ 1/16 (Translating) =3/4 × 16/1(Change of division sign and multiplied by the reciprocal fraction) =(3×16)/(4×1) [Multiply top to top and bottom to bottom numbers) Now reduce by canceling the common factor =(3×4×4)/(4×1) 【Cancel 4 from both sides】 =(3×4)/1 =12 The answer for 3/4 divided by 1/16   is 12.
