Equivalent Decimals

How to find equivalent decimals.
Equivalent decimals are decimals that name the same number.
‫الكسور العشرية المتكافئة هي كسور تمثل نفس الرقم‬
Use models and paper folding to find equivalent decimals.
Example 1 :
Are 0.2 and 0.20 equivalent decimals?
Activity
STEP 1
Shade 0.2 of
The thenths
model and 0.20
of the hundredths
model.

twenty hundreds
2 out of 10
20 out of 100
STEP 2
Shade 0.2 of
0.2
The tenths model
and 0.20 of the
hundredths model.
Then compare the
models.
fold

So, 0.2 and 0.20 are equivalent decimals

Example 2 :
Essam said that QR 0.30 is 3 tenths of a riyals
Ahmad said that QR 0.30 is 30 hundredths of a riyal
Who was correct ?
‫ هاي‬QR 0.30 ‫– قاال أحماد أن‬
‫ أجازاءمن عشارة أجازاء مان الا‬3 ‫ هاي‬QR 0.30 ‫قال عصاام ان‬
‫ من منهما على صواب ؟‬.
‫ جزء من مائة جزء من ال‬30
Compare the models
Essam used a tenths model to
show QR 0.30=3 tenths.
Ahmad used a hundredths
model to show QR 0.30=30
hundredths.
Each column is
Equal to 0.1,
or one tenth,
of a riyal.
0.3 of a riyal
Each column is
Equal to 0.01,
or one hundredth,
of a riyal.
0.30 of a riyal
The two models show that 3 tenths of a riyal is equal to 30 hundredths of
a riyal. So, both Essam and Ahmad are correct.
